Social isolation makes people stressed out and forgetful, but soon a drug could cure this problem. Late last year, scientists isolated a brain enzyme that triggers the "loneliness" feelings during periods of solitude. Replenishing that enzyme in the brain could enhance memory and relieve stress when you're spending a lot of time by yourself working (or space traveling).

People don't need people. People need drugs.

I can't wait to see that hallmark.
