Well here I am at 83 with my wife 85 and we're still bicycling together. This is the highline canal in Denver Colorado. I also run a very successful Facebook forum for older riders. You may be interested that it was I and Joe, the original owner of the entire forum, who started the 50 plus forum. The language of the 50 plus forum on the index page are words that I wrote. Joe eventually sold the forum at a nice profit.
