What's been the most infuriating thing about this to me is that I've always been the complete opposite my entire life. I never cared about germs/contamination. I washed my hands when they were dirty and I showered when I needed a shower.

There really wasn't a trigger...I wish there was a point or life event I could point back to, but there really isn't. I got my MBA and began working in Silicon Valley and I lead a pretty normal/uneventful life. This thing just crept up on me.
