Our local authority leisure centre runs classes for the over 50's.A one hour keep fit session with an instructor is Ł1.75 and not too taxing. There are about 25 ladies who go twice a week. It's a bit of a social occasion too.

Can you leave your son for about 40 minutes to do a walk maybe a couple of times a week ? I know I have forced myself to say hello to people I pass on the way even if I didn't feel like being sociable. After a while it becomes more genuine. A walking club maybe ?

How about a make up lesson in one of your local department stores?
