text: what retired people can do? old father 79 years feels boring socializing is great, always. look for anything in the local community. he can also write down interesting and funny things from his life. share lessons learned and wisdom gained. this is something i wish my grandmother had done more of. she is gone now and i still have so many questions to ask. if it is agreeable with him, even remembering all your favorite jokes and making a small journal of them would be fun. i dog or cat to take care of is terrific for improving the quality of life for anyone and gives companionship to those who don't get out much. growing plants, herbs or flowers. (he can give the flowers to those he loves. hint, hint ;)
