As Old Geezer says, it's the problems that come with old age that will stop people pursuing their interests/hobbies. Arthritis has curtailed my interest in oil painting but photography is still my main interest plus carpentry, gardening and Diy. There are many pastimes out there, the few I've listed plus amateur dramatics, rambling ( walking not talking), Dancing, fishing, music, computing, sport and keeping fit; but probably the most popular would be those that come under your title hand crafts.
