Great resolve to your problem Moses!
Or perhaps I should say:
BRILLIANT!
My mom and dad are in their eighties and still living in the house I grew up in. Dad will still pull out a ladder and work on the roof etc. and mom is having a little trouble getting around. My brother and I are very worried about them so I know how you feel. We want them to be active but we also want them to be safe.
Speaking of old guys, when I work in my dads air condition company he made a deal with an old local doctor who was a Korean war medic to patch us up whenever we got hurt. Some times we would drive half an hour to get ot his office but it was always faster than emergency because he would bypass everyone in the waiting room and see us immediately. He was an old grump but did excellent work and I could tell he happy to see us and get a chance to remember his repair skills. I think it was nice for him get a break from listening to old folks complain about their aches and pains and do some light surgery. Picture two smelly, dirty, construction workers rushing into an old doctors waiting room with blood dripping and wounds wrapped in paper towels and duct tape.
Unfortunatly Dr, Block is no longer with us.
I remeber once I almost cut my thumb off... he took a look at it, pointed to the sink and said "you better wash that, you won't like it if I do"
