I really feel you're only as old as you feel. I'm 63 and still feel 40, well almost anyway. I hiked the Grand Canyon rim to rim 3 years ago and climbed tow 14,000 foot peaks last summer. I'm planning some backpacks in Utah canyon country in the next few weeks and another trip into the Grand Canyon in 2010.

I know some folks aren't as fortunate with their health as I am at my age so I am grateful for all the time I can get and hope to keep going for years to come.
