Are you from Califonia? They must've been adding something to the water so their entire population is zombified... If you look at most any solvent sold in home improvement stores all over the country you would almost certainly find some note kinda "Not for sale in California"... It is definitely harmful if you have to breethe it 5 days a week for full 8 hours but sniffing it occasionally from time to time is no more harmful than going outside and taking a breath of "fresh air" filled with all kinds of pollutants. Even pure hydrogen dioxide is lethal in proper doses... --- ****************************************************************** * KSI@home KOI8 Net < > The impossible we do immediately. * * Las Vegas NV, USA < > Miracles require 24-hour notice. * ******************************************************************
