"Once you get out of the drinking buddy stage, a lot of guys will just settle into their work, and they’ll have a partner, and they kind of just don't pay much attention to anything beyond that," he explains. "Women are usually better at paying attention to their social relationships. Now, that's a gross generalization, and some men are really socially aware, and some women are clueless, but by in large, women are socialized more as they grow up to pay more attention to relationships."
Dr. Waldinger adds that his work on this study has made him more cognizant of the role his wife plays in commanding their social life -- and to what extent he's doing his part.
"I have to actually think to myself, 'Am I keeping up with my friendships, with my individual friendships?'" he says. "I have to pay a lot more attention to my individual friendships, or they would just go away."

In his TED Talk on happiness, Dr. Waldinger mentioned that over 80% of millennials listed "getting rich" as a major life goal, followed by 50% wanting to be famous. These ambitions are all well and good... except they aren't proven to lead to health or happiness. So they're not all well and good, actually.
