I Just touched a fully HOT "Soldering Iron". . . . . Am not feeling a thing and am typing as usual.
PS : some place slightly below the plastic . . . . . my fingers (3 of them) did brush against the metal, was surprised as I had already soldered at least 6 to 7 contacts & a few more after that... I do have a UPS, So no question of BESCOM saving my fingers..
