Columbia has long had a penchant for the hazardous.

Shopping carts, to your hands
.  Just by touching them, you risk diarrhea and worse.

Sleep deprivation, to your heart.  Nearly everyone with a college degree will probably have a heart attack 50 years after graduation.

Cancer drugs, to your fetuses.  But now, the miraculous techniques of freezing means you can prevent the first and save the latter.

Vermin, to your asthma.  Oh, and also to your general sanity.

Rocks, to carbon dioxide.  Nothing says “run away” like the word “sequestration.”
