marc siegel joins us.destroys an airport hangar. >> an eye opening study showing aling between two debilitating diseases. new research showing depression increased a person's chance of developing parkinson's. dr. marc siegel is a member of fox news medical "a" team. one million people in the u.s. diagnosed with parkinson's. 10 million worldwide. what link has the study established between that and depression? >> this is a very, very important study. i want people to know what to look for in parkinson's disease. tremor a stiff gait, problems writing and using your hand and thinking and behaving. parkinson's disease affects a lot of systems in the the body. how do you know that you have it. this amazing study literally looks at everybody in sweden over the age of 50. can you manage that? everybody over the age of 50. they discovered if you had depression and they followed people for 6 years. if you have depression your chances of getting parkinson's disease is three times what it is if you don't have it. the

marc siegel says this. >> you could sustain a brain injury and get a head injury that way.clear there is no way that you could sever your spine by bashing your head against the wall or side of a car or anything like that. that is not going to be the cause of the severed spine in this case. >> the the truth is we don't know what happened to mr. gray, the same way we did not initially know what happened in ferguson missouri. it's fine to report about possible evidence if you see a piece of paper and that's hun it, you have got to report it but it is irresponsible to speculate about it. it's also irresponsible to make insane statements, trying to justify vigilante violence. that's what we have been hearing all week. the litany of excuse-making is excruciating. the rioters are angry because america is a country of mass incarceration. people who burn down buildings and loot are just misdirected folks who feel hopeless. and if you feel hopeless it's okay to riot. you see it's really not the fault of those who commit crimes. it's the fault of america because we don't provide jobs

marc siegel took part in the warrior mountain bike ride on president george w. bush's ranch., dr. siegel caught up with the former president. check this out. >> i want to start by asking you about your book 41. because in that book towards the end you talk about how your father wanted closure from jumping out of a plane over the pacific. and he wanted to repeat that until he got it right. >> yeah. >> what can we learn from that? >> you can learn this doc, that one should never stop living life to the fullest. so in the book "41," and thank you for bringing that up i went to see "kiss my dad good-bye." i was convinced that he was going to pass on. took my little girls there, and laura. and about five months later, he is jumping out of a helicopter at the age of 90. so the will to live is very important for your health. and obviously you've got to make good choices in life. but i think the idea of a guy who can't walk and near death, jumping out of a helicopter at age 90 is a pretty clear example of the desire to live to the fullest. >> veterans go overseas to protect us they c
