I don't ride one but rather two recumbents; so far, though, just one at a time. As stapfam suggests they are fine rides while a person is still alive but likely not appropriate afterwards.

In the world according to me a recumbent is likely not appropriate for riders who are perfectly happy with their conventional bikes but, for the rest of us, can lead to many thousands of miles of happy riding.

A few recumbent riders, often noobs, get all knicker twisted defending their choice as right for everyone. Please cut them a little slack just as we do the few conventional riders whose twist goes in the other direction.
