So do a lot of other things. And beyond a certain point, I'm not balling myself up in bubble wrap and living a dull, boring life just so I can eke out another few months on this Earth. I'll take decent care of myself and not do blatantly stupid things. But I'll also enjoy things, and then when it's my time, it's my time. Life is there to be lived.
I may not take quite as an extreme view as Hunter S. Thompson, but he was onto something when he wrote:
"Life should not be a journey to the grave with the intention of arriving safely in a pretty and well preserved body, but rather to skid in broadside in a cloud of smoke, thoroughly used up, totally worn out, and loudly proclaiming 'Wow! What a Ride!'"
