Possible reasons why I did not a get a cold all winter

[ellenkushner]

1) Got really scrupulous about washing hands, esp. after riding the subway

2) Taking 1000 mg Vitamin D every day 

3) Got giant pack of boxes of soft tissues from Costco, still sitting in utility closet blocking access to everything

I'd say #3 is the real factor.

I never take vitamins and only really only remember to wash my hands before preparing meals or when they're actually dirty - AND I bite my fingernails, and I haven't had a cold or flu 10 or 12 years.
