Just as an interesting comment on being 65, I recently took a 6-day, 300-mile "catered" tour on the Great Allegheny Passage and C&O Canal Towpath from near Pittsburgh to Washington D.C. This was a fairly tough route, being all on trails and with the C&O in particular not being particularly smooth (we actually had one day of a mudfest due to overnight rain). I expected most people to be 50+ with myself near the top of the age spread, so was surprised that I was only the 6th-oldest of 12 and there were only 4 people younger than 60!

It does me good to be around so many others in my age bracket who are in such good health and condition to tackle something like this, and everyone went through with flying colors. And I still remember once when we rode up some really steep roads to make a side-trip to Antietam; I thought I was leading the way to the top when the 75-year-old of the group just blew me away! He must have just been on a faster bike...
