'Super-agers' study may reveal secrets to staying young

Social connections

Abbott confesses that prior to entering the retirement home, she was not doing so well. After her husband died, she lost weight and felt lonely.

"One of the big reasons I like being here is I got tired of eating by myself," says Abbott.

She clearly thrives on social contact. Now, she plays golf every Monday and rides the bus to church on weekends.

Abbott leads the welcoming committee and knows everyone, from the gay couple who just moved in, to the woman in her 90s who nearly died but is now lifting weights again in exercise class, to the woman with the raven hair who had a tryst with a doctor 20 years her senior, then married him, and has stayed married to him for some 40 years.

She recounts these vignettes without malice, exuding pure delight at knowing the details of others' lives.

There's some science behind this, too.

"Epidemiological studies show that people with a lifetime of cognitively stimulating activities and social connections are much less at risk for cognitive decline as they age," says Loewenstein.
