I am also 46 and can not do much of anything physical with my hands anymore, such as sand, paint, use a screwdriver, etc. Years ago I switched to an ergonomic keyboard (Kinesis Advantage 2) and a vertical mouse. Neither bother me at all, I can type and use the mouse just fine all day. Unsure if the two are related. Does the pain I feel from sanding indicate I'd feel similar pain with a non ergonomic setup? Not sure. But I am glad I made the switch, just in case.
