david samadi, professor of hofstra school and a member of the a-team. why the reason for the outbreak? >> a huge concern and if you remember, 2000 and 2001 we said it's the end of this outbreak. now, a lot of the kids are not getting vaccinated. so out of 32 out of 39 cases nobody got vaccinations. sometimes you need a booster, so some of the people who have been vaccinated they needed to have some boosters. but the huge problem is either because of religious studies or the theory it may cause autism, which is a huge mistake, people are not getting the vaccines. we were done with measles. ten years ago that was the end of the outbreak. before vaccination, and now we're back in again. or either from the southern border a lot of the kids are coming in that haven't been vaccinated. they're getting in and spreading it to other kids. >> let's talk about it for those avoiding vaccination how dangerous. >> i think it's quite dangerous. i would love for people to come on my twitter and have a chat. i would love to learn exactly what religion bans you from getti

david samadi. good morning.ep, we're certainly not getting it here. many americans -- >> i'm sure you got seven hours of sleep last night. >> is seven what you really need? >> that is the minimum you need. this study published in journal of sleep they looked at about 100,000 americans and they realized we're not getting enough sleep. >> why? >> partly because of our work, always on the run and interruption because of stress and everything, and that's not healthy. lack of sleep can kill you. why and how? because it really changes everything. think of the brain as a very complex building. what happens during the day in all these lobbies? people are walking around, the trash can starts to fill up. what happens at nighttime? the cleaning people will come in and start cleaning up the trash cans. the same thing goes on in your brain. while you are sleeping during those seven hours these cells are running around trying to clean up free radicals and et cetera. when you don't get enough sleep your memory is not going to
