Hey now, thats my line!  At 71, I find I must use a strong lens to 
inspect circuit boards for cracks and cold solder joints these days.

I have the tools, after 55 years of chaseing electrons for a living, who 
doesn't, but trying to keep track of which hole in an 80 pin connector 
that I actually have the pin plugged into gets to be pretty darned 
tedious & mistake prone.
