Last week I caught my first cold of 2016.  I know, first world problem, right?  But in typical introvert fashion, it made me reflect.

To be clear, I wasn't reflecting in a melodramatic, Nancy Kerrigan "Why me?" sort of way. Instead, I wondered why I've only been sick once in 10 months, while others will tell me how they're constantly getting sick.  I also remember hearing that "having 4 or more colds a year is normal."

Yeah, about that.
