You're never too old! That's my motto. If you can still do what you enjoy doing then go ahead. I've always loved bike riding and walking, but unfortunately due to two major operations within 6 months I was forced to give up both pastimes including my line dancing which I loved. But, since both ops were successful I am thankfully getting "back on my bicycle" as they say.
I have little time for people who say, "Oh, I can't do that, I'm too old." Age is just a number and there's truth in the old saying that you're as old as you feel. I'm not recommending we all get onto bikes or go skiing or whatever, but as long as you are active then go ahead and make the most of the golden years.
Just before I had to temporarily give up my riding a friend and I packed our fold-up bikes in the boot of my car, caught the ferry across to Tasmania and had a ball cycling along some of the most beautiful tracks in Australia. The pic was taken in Strahan on the west coast. We stayed overnight in a lovely little cottage that I knew was haunted as soon as we went in the front door. Needless to say I saw the ghost that night--but that's a story for another day.
I do volunteer work and go into the homes of disabled people to help them with their computers and internet access, so see a lot of those less fortunate than I because they are unable to get out of their wheelchairs and enjoy active pastimes. But that's not to say they don't make the most of their lives doing what they are able. I have the utmost admiration for them, especially the seniors, as they surf the net, enjoy communicating with their friends and family, and generally enjoy making the most of their time.
