When I was young--5 or 6 years-old--my school used to take a group of us to visit the elderly at an "old folks home."
I loved going and making them laugh, and signed up every week to go as often as I could. I still go past this home occasionally and it gives me warm memories.
I haven't yet worked with the elderly population professionally, but I know that I will someday. I think the elderly have so much knowledge and insight about the present, but nobody listens to them very often.
The elderly often scare people because people are afraid they too will grow old. But alas this is inevitable and everyone must evolve.
