I just read this on Cnn.com/Oprah.com:

A study from the University of North Carolina found that women who got several hugs a day from their husbands had significantly lower blood pressure than those embraced less often. Another study using fMRIs showed women’s brains to be far less reactive to the threat of mild electrical shock when holding a loved one’s hand versus a stranger’s.

Bring a spouse the next time you go for electro-convulsive therapy.
