My neighbor is 89 and still works part time as orthodontist for children here in Toronto. When he was 6, his job was to run from one outpost to another delivering messages during World War 2. He volunteers weekends removing trash from the public parks and cleaning up our streets of litter. I am teaching him how to play professional chess and we had plans to go to professional tournaments (but covid hit so maybe next year) and he is picking up really well.
