Your dad got hydrofluoric acid for you when you were 10?

I've been around several things that aren't exactly safe, H2SO4, HCl, H2O2(Not the weak 3% stuff, I'm talking about 30% - 50%), but I woudn't even want to be near HF, I heard if you spill it on yourself it sucks the calcium out of your bones, and if not treated in time you will probably have to have a limb amputated.
