I notice all the sneering aimed at people in their seventies and more, and their apparent lack of knowledge about real life.
I considered my local community, with plenty of young families and adults of all ages and voluntary support groups, and my own connection with the village hall committee, library support group and village clean-up party. These are all organised and run by people in their late sixties and seventies, and even eighties; the library group battles to keep the library open, and funds all the free activities provided for toddlers, and children on Saturday mornings. Not one parent of these children ever attends any fund-raising functions, or attempts to help with activities; same with charity evenings at the village Hall. The litter pick up group, same age. The Primary School PTA, which used to flourish, has collapsed due to lack of support, from over four hundred pupils, and not all parents work full time. Many of the former PTA members have graduated to other voluntary and charitable activities, such as Day centres and Care help.
So don't sneer quite so much at the elderly; they contribute a great deal to community life, and actually do have experience of real life, now and in the past, whether their hair is blue, pink or grey.
