When I had my wisdom teeth out, there was no way I could game without my Vicodin. Or was I prescribed oxycodone? Whatever. It hurt like hell and gaming was the last thing on my mind.
Ironically, when I tore my foot open by accident last August, I was mostly upset that I tore a hole in one of my good pairs of socks. Yeah, it hurt to have a two-inch-long gash (maybe 5 mm deep? Dunno...) in my foot, but the sock and shoe couldn't heal on their own.
Yes, I realized I just used both English customary and Metric systems in one sentence. That's 'cause I'm 'Merican! In AMERICA, we learn both systems! Though the extent to which we learn Metric depends on the focus of our studies...
