because for every site or post that say's it will last until the end of days....there's equally as many that say better shoot that shit by the end of the week. I've been wondering this question as well.....as with so many things in this field, there are so many contradictory opinions and statements that it's hard to gauge what's what? I mean, they say if your IGF get's breathed on too hard it turns inert......yet, and anyone who's ever worked for a parcel service will back me 100% on this, when you get your package in the mail you can bet your ass that little parcel's been tossed the fuck around on the way to your house. So who knows dude...who knows.
