Several times I have heard a rumour that a 1/3 of people who serve 22 years in the army won't live longer than 65 due to the type of physical training they done in the service. Apparently, your used to short sharp sessions which work the bottom half of you're heart, so when you're out of the service, it slows down and some how you die by the time you are 65. This I think is complete tosh. But, hey, I could be wrong. Now, I'm sure everyone else has a bollox rumour that a lot of people may have believed, but to sit and think about it - just sounds like nonsense.
