What are some interesting science hobbies for retirees?

[Grampa Dee]

How did you find PF?

I did a search for science forum

Hello:

My name is Andy and I'm interested in science in general. I will be retired next year and am looking for some hobbies...; this forum seems to be an interesting place to start. Hope to have some thoughts and questions to get into some of the conversations...
