First, Phillip B, you said "The problem with scary statistics is that numbers don't factor in how tough people can really be. My posts concerning pursuit of an active lifestyle are intended to encourage people to pursue the activities they enjoy. If you don't agree with my perspective, that's okay... you're entitled to your opinion just as I am mine."
I'm sure we all know, or have heard of, people who've smoked 3 packs a day and died in their sleep at 98 years old. People can be tough, and people can also be lucky. We can also be smart or stupid, aware or unaware, and conscious or in denial. I favor tough, lucky, smart, aware, and conscious, and I try to discourage the other five. I think that assuming that statistics drawn from large numbers of people should not be ignored because "I'm tough" or "I'm lucky", is flirting with some of those other characteristics I try to discourage.
I just finished a fun (though cautious) ski week while 8-9 weeks post-opOHS/AVR and while on Warfarin, so I obviously agree with you about encouraging people to pursue the activities they enjoy! But I think there's a difference between accepting risks and denying their existence.
I think cardiac rehab is going to be interesting for me, because I've been doing a fair bit of it on the slopes, before the CR course starts! I wore a heart monitor, and generally rested until my HR was down to ~110. (I'm usually around 85-105 resting, post-op, and just LOOKING at a ski slope gets me up to 110!) When I'd stop, I'd check my heart-rate, and I kept it <~125 the first day, <~135 the second day, saw it hit 140 maybe twice the third day, and seldom saw it break 130 the 4th day, although I was skiing faster, harder, for longer "bursts", and for hours longer overall. (~17,000'+ of vertical the 4th day, roughly 11,000' for each of the first 3 days. My pre-op range was ~20,000'-34,000' per day.)
I'm expecting to be bored for the first few sessions of Cardio Rehab, but I may be surprised.
I've never skied in a helmet before this week, and it was remarkably fuss-free, so I will probably keep using it, even if I come off Warfarin before my late-March return to Whistler (as I hope).
