Memory loss seems to be part of the equation as we get older...especially short term memory. I keep a pen and notepad at 3 or 4 locations in the house/garage/workshop, and jot down things I need to do as I think of them. Otherwise, I am likely to get involved with something else, and forget about what I was thinking. That way, I can keep a running list of things that need to be fixed, etc., and prioritize them as to urgency, etc., and always try to keep a couple of minor indoor "to do's" on the list to occupy some time when the weather is bad.
