The study was published last month in the New England Journal of Medicine.

The study showed that when a person becomes severely overweight, there is a 57% increased chance that one of their friends will be, too.

A sister or brother of the overweight person has a 40% increased chance of becoming fat.

The increased risk for a wife or husband is a little less than that.

Every year, these allergies causes about 60,000 cases of anaphylaxis.
