Things I have learned.

1. If you are sick, please, please please do not come into lab. Everyone else will refuse to stand within a 10 foot radius of you. Except, of course, your rotation student who is forced to spend lots of time breathing in your germs.

2. If you are trying to help said rotation student with an upcoming presentation, do not get her sick.

3. Denial (and orange juice, sleep, and lots of tea) can help keep the germs at bay.

4. However, denial can only prevent the full blown cold. You'll still feel vaguely sick. And it still sucks. And the full blown cold is bound to hit at any moment.

Moral of the story: Don't spread your cold. Health first, work later (or just work on whatever stuff you can at home).
