What kind of training do they go through in Texas for two weeks, he has some heart issues, will that hold him back from going. How good of health do you have to be in, he is 56 years old, has had 5 heart attacks, and has had 3 stents put in. He doesn't think that it would be an issue, and I disagree with him, I say that they will put him through some tough tests in Texas to see if he could handle it. Any information would be appreciated. thank-you
