Something that has always interested me is why we behave the way we do. Recently there have been a lot of discussions about tenancies and traits that jumpers seem to have in common. I was thinking about heart rate recently. What is everyones at rest heartrate? Mine is really low, usually upper 40's or 50 bpm. The only people i know that have a similarly low rate is a few skydivers and a few athletes. I've never taken my heart rate at the X, always busy preparing for the jump. It would be neat to hook up a monitor though and watch it to see what happens at different stages.

What about you guys? What is your at rest heart rate?
