Okay, here are the rules for OFA (old farts anonymous):
[compiled from my own experience and my medico wife's advice]
1. Double the number of lamps and wattage of the bulbs over your workspace.
2. Get a proper chair, your back will rebel if you spend a few hours in the same position, now that you are ooold.
3. Invest in a gaggle of "helping hands"-- don't ask your hands to be still when you know they can't.
4. Get a good magnifier, strong. Eye strain is your weakness, so don't ask too much of yourself- that's vanity.
5. Aging screws with your internal thermostat- dress for the temperature whether you think you need it or not.
6. Build a spray booth. You need it.
7. If you haven't noticed it already, alcohol in any form effects you differently now. Watch it.
8. Naprosin (naproxen sodium) is your friend.
