VERY SCARY, but I tend to make it my business to KNOW about what I am about to do, if it's cycling, or studying in a new direction, or rebuilding an engine ... don't matter, I research before I try anything. The responsibility is not ours to carry for them. Sad, scary, but true. Unfortunately those noobs will learn the hard way when they need to go on gyno-reversal or strap a pair of man-tits for life.
