Who you spend time with has a huge effect on you,including your mental, physical, and emotional health.

 

In fact, Jacobs also mentions a 2007 study from the New England Journal of Medicine in which scientists concluded that gaining and losing weight can be socially contagious.

 

A person was more than 57 percent more likely to beobese if he or she has a pal who became obese.

 

The same researchers of the study also say that happiness can spread between friends.

 

This may mean that your friends being stressed out can affect your own levels of stress.
