I hear you guys, 10 years ago I could solder surface mount components and see if there was a solder bridge between 2 legs. But now a days if I don't have a good light source soldering a wire on to coil becomes hard to see.  .And now i need a magnifying glass to read a schematic, I have just worked out why I like schematics in pdf format, because i can zoom in and read the small writing.
