>> texting -- it's been around for awhile, but when it comes to text etiquette, most of us are in uncharted territory. [ cellphone vibrates ]

[ cellphone clicks ] sorry. was that rude? most teens in a recent survey say yes, yet for some reason, we still do it. alexa explains. >> when is the wrong time to send a text message? >> obviously, like, if you're in class. >> like, at the movies. >> way late in the evening like, waking somebody up. >> when you're in the car. >> probably dinner, 'cause my mom, like, hates me when i start texting and she's trying to talk to me. >> okay, we know it's wrong to send a text at school, at dinner, or when talking with a friend, but have you ever done it? >> yes. >> yes. >> yes. >> yes, but i've never sent a text at school. >> margaret sullivan is with textplus, a mobile app that's very interested in texting trends. so it did a survey and found that the average teen sends 100 texts a day. that's about 3,000 texts a month. here's what else the survey

found... >> 75% of texters say that it's rude to talk and text at the same time -- to text in the middle of a conversation -- but 50% of kids say they've done it. >> but that particular rude behavior may be changing because of peer pressure. >> given how much teens are texting today, people might be shocked to find out that other kids are calling one another out on their rude behavior. so we actually have users who've said that, in the past, when they're talking to a friend who's texting and they're texting right in front of them they'll shoot them a text saying, "you're being rude." >> given all the texts that are sent every day, it's not surprising that 85% of students admit to texting while in class. but you may find this surprising... >> a lot of those students have told us that it's their parents who are texting them during the class and during the school day. >> most adults don't think they're encouraging bad behavior. they send the text thinking the message will just wait to be read at the end of the school day, but no kid is going to wait

to read a text. what's the point? >> so it's instant, it's fast, it gets to you right away. >> yes, texting is a useful and powerful technology, but with power comes responsibility. sometimes we're texting so fast we send messages to the wrong person. >> so, if you're sending about a hundred texts a day, you've got to be typing pretty quickly. so count to three, look at who you're sending it to and make sure it's the right person and then press "send." >> i was supposed to go out to a party with my friend, and i didn't want my brother to come but i sent it to him instead. oops. >> i was messing around with my friend at school, and i accidentally sent it to the wrong person, and he took it the wrong way. >> me and a couple friends were texting about a surprise party and i accidentally sent the text to the person who the surprise party was for -- ruined everything. it was terrible. [ chuckling ] i felt so bad for so long afterwards. >> i was trying to text my girlfriend, and i ended up texting my ex-girlfriend a very intimate message, and it did not

end well. >> so, i was really mad at one of my guy friends because he was not doing a project with me the way i wanted him to, so i kind of cursed him out to my friend and it turns out i sent the text message to him, so i'm not gonna do that on text message anymore. >> the most common text misfire is sending "i love you" to the wrong person. and while we're on the subject of dating... >> so, if you're gonna ask someone out on a date via text message, there are a couple things to keep in mind. one, personalize it. make sure that it looks like it was actually meant for this person and that you didn't just send out a blanket e-mail to everyone, hoping for one date. >> and here's another etiquette tip -- don't ask someone out who you've never met in person. that's just plain tacky. think of texting as a tool for quick communication, not a replacement for communication. >> take some time. texts are important. it's of course important to stay connected with your friends, but you should always put down the phone and make sure that you're staying connected with the people around you.

>> and remember, don't say anything in a text that you wouldn't say in person. it's easy to be mean in a text and it's just as hurtful. >> coming up, i'm going to show you why trying to play injured is a technical foul.

>> sports can be dangerous, and not taking the right precautions can put you in the doctor's office. diyu has the story. >> what comes to mind when you think of a dangerous sport? football? hockey? maybe even rugby. but i bet basketball wasn't at the top of your list. meet rj mehan. he knows firsthand just how dangerous the sport basketball can be. >> i've pulled a couple muscles. actually, recently i just got an avulsion, which is when you pull

a muscle and it pulls out a piece of the bone, too. >> no stranger to pain, rj had to sit out earlier in his seventh grade season because of a broken arm. >> i went up to get a rebound, and i fell -- someone pushed me from behind. i fell. i went to catch myself, stuck my arm out, and i just felt, like this jolt of pain go up through my arm. >> and rj is not alone. between 2005 and 2011, experts found that 1.5 million high-school basketball players were treated in emergency departments. that's certainly a lot. in an attempt to keep sports safer, many schools are hiring people called athletic trainers. >> we're there to prevent injuries and evaluate them quickly, treat them immediately, and try our best to make sure that, as we return them to play, we do it in the most safe and efficient way possible. >> unfortunately, not a lot of schools have athletic trainers for their sports teams. >> in the high-school setting, about 42% of u.s. high schools have athletic trainers.

in the middle-school setting, i think it's even less. >> whether your school has an athletic trainer or not, there's one thing to keep in mind -- if you're hurt, don't just tough it out. >> when you're feeling those aches and pains from sport whether it's your knee or your back, and it's just not going away, it's hampering what you're trying to do on the court. >> if you don't follow the recommendations and you cut short your healing time, it really could keep you out for the rest of the season. you could be re-injured or you could have a career-ending injury. >> experts say that there is more than one way to avoid injury during your sports season, whether it's basketball, football, baseball, or even tennis. >> many of the injuries in basketball are preventable, and the ways to sort of avoid injury are gonna be stretching and conditioning, proper warm-up and cooldown afterwards. >> professional athletes can spend up to an hour getting ready for a game -- sometimes more. so get a good warm-up in before playing. and remember, if it hurts, stop

and tell your coach or parents. >> we're here to help. we're here to make sure that we can get you back as quickly as we can. and a lot of times, you're not gonna compete at your best until you're feeling good. >> having an athletic trainer on your team is surely a slam dunk. for "teen kids news," i'm diyu. [ bat cracks ball, crowd cheers ] >> anyone who has ever followed baseball is probably familiar with the cy young award, the award given to the best pitcher in the american and national league. this award was named after hall of fame pitcher cy young. cy pitched in the early days of baseball, back in the very early 1900s. he has the most career wins of any pitcher in all of baseball history, with 511. however, ironically, he also has the most losses of any pitcher in baseball history, with 316. i'm matt with "teen kids news." >> when it comes to improving grades, scientists in spain say girls have a leg up. they compared girls who walked

or biked to school with girls who caught a ride. on average, the more physically active girls scored four points higher on math and verbal tests. the researchers say exercise made the difference, though they aren't sure why. it may have to do with the increased blood flow to the brain. and here's something interesting -- exercise doesn't have the same effect on boys. i'd like to drop out of high school and get a meaningless job that makes me feel bad about myself. i'd like to fall victim to the old boys' network. i don't want anybody to notice me. i just want to fly under the radar. i want to splatter against the glass ceiling. i don't have an opinion. i want to be a straight "c" student. i'm going to be a biomedical engineer. [ girls laughing ] i mean, i want to succumb to peer pressure all of my life. i'm going to be a best-selling novelist and win the national book award. i'm going to be a marine biologist. wait! i take mine back.

i'm going to be a biomedical engineer. i think i'll be the president. i'm going to be secretary of state. world-class chef right here. race-car driver. artist. paleontologist. film director. surgeon. teacher. scientist. olympian. i'm going to be the boss. i'm going to change the world.

>> in this week's "college & u," nicole takes us to a school that prides itself on giving back. >> washington, d.c., is the political center of our nation.

it's home to monuments memorials, the u.s. capitol, and the white house. it's also home to one of our oldest schools georgetown university. shortly after the american revolution, the founding fathers saw the need for an educated and virtuous class of citizens to lead the young nation. the ink had barely dried on the constitution when john carroll founded what would eventually be known as georgetown university. but georgetown's roots go even deeper into history. it's the oldest jesuit university in the country. jesuits are known for a commitment to learning and intellectual inquiry. they've been around since saint ignatius started the society of jesus in europe back in 1540. >> he wanted a group of priests who would not be bound to a particular church or parish or town. he wanted to start a religious order of men who would go anywhere where the needs of the world were greatest. >> so, what does it mean to be a catholic and jesuit university? >> to be a catholic and jesuit

university means to be committed to academic excellence, to be committed to exploring one's faith across different faith traditions -- catholic protestant, jewish, muslim orthodox christian, or people who may be struggling to find their faith. >> while most of the 7,500 undergrads here come from catholic or other christian backgrounds, all faiths are welcome. >> actually, right if you go into healy hall, there's the jewish rabbi, the muslim imam, and the head priest all in the same building -- offices right next to each other. >> georgetown is actually one of the first universities in the united states to have a muslim chaplain -- a full-time muslim chaplain. >> and the school motto is utraque unum -- "both into one." can you explain that? >> yes utraque unum it's a latin phrase -- "from the many into one," or "from the one into the many." so, for instance, we strive to be one community here at

georgetown, but yet we're a very diverse community, and we welcome a diverse student body -- one and many. >> students are encouraged to uphold the jesuit ideals of being active on behalf of others. so it's no surprise that georgetown grads fill the ranks of service organizations like habitat for humanity teach for america, and the peace corps. >> it's a great school academically, but also the commitment to serving others and using your education to further the good of the world and humanity. >> there's a whole variety of programs to get involved in depending on your interests and language abilities, oftentimes. so you can take what you learn in the classroom and apply it to social justice in d.c. >> georgetown has a very important saying, and that's "men and women for others." >> there's yet another latin phrase that you hear students use to describe their georgetown experience. >> it really fosters cura personalis or, you know, the formation of the person as a whole. and it emphasizes each aspect -- so your intellectual development, your spiritual

growth and development, and academic growth and development. >> and that leads to leadership. for example, the georgetown class of 1968 delivered three future presidents -- arroyo of the philippines, cristiani of el salvador, and our very own 42nd president, bill clinton. georgetown has four undergraduate schools and offers degrees in more than 40 majors. and most students opt to spend at least one semester studying abroad. its world-renowned school of foreign service has trained generations of diplomats. [ crowd cheering ] georgetown athletics are world-class, too. the teams got the name hoyas back when every student was required to study greek and latin. so, do you have a latin phrase for that, too, that you cheer at games? >> i don't -- well, we do. it's a latin and greek phrase called hoya saxa, which has a lot of disputed origins. if you were to translate that directly from the latin and the

greek, it would mean "what rocks." >> i've met some great people, i've had fantastic professors, and i'm having a great time. >> one of the deans here truly captured the spirit of the school when he said, "coming to georgetown is a privilege, and with that privilege comes the responsibility to give back." for "teen kids news," i'm nicole. [ dramatic mid-tempo march plays ] >> the medal of honor is the highest award for gallantry in the u.s. armed forces during time of war. in american history, we have two father-and-son teams that have received the medal of honor. first, we have arthur macarthur during the american civil war. 1864, he was a 19-year-old lieutenant... >> who helped lead a charge up missionary ridge in tennessee

and planted a flag on the confederate works, and for that he received the medal of honor. >> and then later, his son douglas macarthur received the medal of honor in 1942 for his defense of the philippines. >> the other set was theodore roosevelt and theodore roosevelt jr. theodore roosevelt jr. received his medal of honor in world war ii because of his actions at normandy and the invasion of normandy on d-day. he helped secure the beaches and, actually, when they found they had landed at the wrong spot, said it didn't matter -- "we'll start the war from here." his father didn't receive his medal of honor until many years after theodore roosevelt jr. had gotten his. theodore roosevelt was given the medal of honor posthumously for leading the charge up san juan hill during the spanish american war. ought i could ignore it, and i wished it would just go away.

[rock music playing] it was my adhd. and like many kids with adhd i didn't outgrow it. one of the issues i had was not being able to focus. i would read and i would reread the same sentence. you'd read it over and over and over again. and then, five minutes later i wouldn't know what i just read. it wasn't sticking with me. it wasn't sinking in. and that, to me, was really frustrating. as i got older i was still having that issue. and that's when i knew i needed to talk to the doctor. announcer: if you were diagnosed with adhd as a kid you might still have it. find out more. take a quiz at ownyouradhd.com to help recognize the symptoms like inattention, impulsivity, hyperactivity, then talk with your doctor. i take responsibility for my adhd. it's your adhd. own it.

>> hooplaha's motto is "life

with a smile." their website features good news, inspirational stories, cute pictures, and fun videos. sound familiar? since "teen kids news" has a similar mission, we're presenting you with our "hooplaha pick of the week." [ up-tempo music plays ] >> we noticed that there wasn't an ice-cream truck in town. and i think, for us, like, a lot of childhood memories started with being at the local pond and, like, hearing those sounds and, like, running towards the truck. and we were talking about that one day. then it was like, "well, let's do it. like, let's make a business." [ mid-tempo music plays ] >> music we decided to start college creamery because while all of our friends were looking for internships and jobs, we just wanted to do something unique. and all three of us thought it would be great to do something together and something that could help to contribute to our own educations and paying for our own college expenses. >> we went to school together at uvm for a while, and that's where we came up with the idea. and then, the first person we called was taylor. >> i'll never forget that phone

call. i was in the common room of my freshman dorm, and they told me this idea, and i could not believe it. >> i think we were originally gonna be cones for college. >> that, yeah. >> but i think taylor came up with "college creamery"... >> you did. >> ...and we all, like instantly loved it, so we just adopted it. we like to donate a lot of money to different education foundations and different causes in the area. we think it's very important obviously, to get an education so we'd like to, like, support other people who are also in pursuit of an education. >> this is a fun way that we can hang out together and start paying for our own educations. >> mm-hmm. >> we do shaved ice, and then we do these bars here, which vary. we change it up sometimes, but we try to kind of keep it like the classic things that you would see on an ice-cream truck in the past. and we've also always talked about possibly opening a restaurant or doing something else with food because we just have a passion for it. so maybe we will end up with a restaurant or a gourmet food store or something like that, so we can continue on with our food ventures.

>> [ chuckles ] >> i hope that, next summer, we're as successful if not more so than this summer. >> that wraps up our show, but we'll be back soon with more "teen kids news." thanks for joining us, and have a great week. write to us at...
