My father is in excellent physical health for 81. He is widowed and retired. I am in search of an activity he can do that he enjoys. He likes to problem solve, to build things, to work with his hands, to help others even. It would be great if he could go work somewhere a few days a week doing something he liked but he is hesitant to try new things. I would like to find something he can enjoy here at home that maybe can be a give back activity. I have scoured the internet for senior activities but all the activities assume someone is old and inactive. I have an active senior who can be useful if I can find the right thing to plug him in to. Any ideas welcome!
