Quite right Ebbie. I did voluntary work for 8hrs a week in a local large hospital for years after retiring. The number of volunteers in that place was phenominal, including cafeteria assistants,coffee shop workers, in-house supermarket assistants, mobile trolley shop(me and several others) library trolley, Listeners in the chapel, ward practical helpers, guides to departments, hospital car service drivers, Women's Voluntary Service Shop (me again on a Saturday evening)etc. It ran into some hundreds. Imagine the cost if all those folk had to be paid. They'd just pack up the services and do without I expect. Retired people are absolutely invaluable to society. But it's voluntary, not obligatory. Not every older person has the health and strength to work, and it should be a matter of choice.
