I do realize that after decades of smoking, or for obese individuals, or those who have suffered injury, it seems tough. You can't sit around for 3 decades and suddenly adopt a challenging fitness regimen and not feel discomfort. But while the crybabies finish drying their tears, I'd like the rest of you to meet Errol Hannigan, AKA Captain Ahab, whose pictures speak louder than any words that I could write: Click his photo above... he's the guy with the bionic leg.
My philosophy is that I don't care whether people take care of themselves or not; just that they be secure enough in their choice not to be continually trying to justify it. The next time someone you know tries to make a lame excuse for...well...just about anything, send them a link to Errol's website.
