Yes there is, but competition for decent jobs in IT is very hard. I don't know where you live but certainly jobs in the London area come up quite often and are advertised in the press. What else can you do (if it's you)?
theres no reason at all you shouldnt but you could perhaps approach places that need IT but tend to involve people of your own sort of age or older, such as libraries, clinics, care homes, some societies...places that arent trendy etc.
