The fear of capsizing thing comes more so when the cardiologist tells you that you need to limit your physical stress to walking and not running and all that kind of junk. As a life long type A it is hard to give it all up totally, so I acquiess to his demands by making sure I can mostly avoid the trying to right the beast situation. I love speed and all that stuff, I just have to accept that there might be a bigger set of guidelines on what all I can take on than in the past. I'm looking for what that upper end of the Bell curve is without having to go test it to see that indeed it happens! When you get really old like me you too may be forced to accept that you can write the check, but maybe your body can't cash it all the time! LOL!!
