What is there to do in Chichester and the surrounding villages?

I'm now a pensioner and have been in the area for 25 years nd still haven't found anything regular to do apart from belonging to a choir. I did belong to some discussion groups a book club when I first moved here but they have all fizzled away. I'm not interested in sports activities, bingo or slimming clubs, so what is there. I'm going crazy just wasting my life away with nothing to do.

Suggestions and contacts please.
