I'm 20, 21 in July. If it's any solace to you older guys on here I am going gray due to a combination of stress (engineering school), caffeine intake ( see previous), heredity (my dad was gray at 28), and alcohol intake (one or two or five homebrews a week, see previous). Luckily, full-sized cans cover the patches so I have a good excuse to rock cans in odd places.
damn, thebikingengineer. Going gray already? that sucks. I'm also 20 and an engineering major. Go figure. I am selling all of my equipment though except for my shure se420's because well money is tight for this college student.
