Hamid,
   I read all of Kevin's posts.   I didn't see anything in there that says he is betting his life on it.   Just that it's worth having the option when it is an option.   I had to chuckle reading your - as usual well reasoned but as usual unnecessarily abrasive  - posts, just days after that guy jumped out of his glider after getting bashed by a jet at 300mph in Nevada.
