Maybe some sort of organised social dancing would be a good idea, seeing as how fat the population as a whole is getting - but I'd say blow the kids, they get far too much, start with the oldest people able to do it. Older people are getting to be so isolated, nowhere to go, no one to see - and at least they would have some idea of how the dances were taught maybe 60 or more years ago.

Elderly singles don't want ballroom dancing - particularly for the women it is far too intimate, but country dancing in a local hall of some kind could be just the thing.

The very oldest people can often respond to songs and tunes even when they have lost the power of speach.

Music and dance would not interest everyone, but the older generations would probably appreciate it more than most.
