Epicurus, who likely lived with young boys like all his male contemporaries did, had the right idea it seems.

Scientists now say that humans live longer if they have more social interactions. Studying fruit flies Chun-Fang Wu and Honyu Ruan at Iowa University found that mutant fruit flies, sharing a home with young fruit flies live longer, are more active and resistant to the effects of physical exertion, heat and oxidative stress than those living with mutants their own age. (New Scientist, 31 May 2008)

These are important findings. While Epicurus might have found boys rewarding to live with, perhaps it will now become acceptable for old guys of a certain age to withstand oxidative stress by recruiting beautiful young models to live in their spare rooms, thus ensuring many happy and active years of companionship to both husbands and wives. A new lease of life, fellers! And please, comments to the effect that the wives could respond by encouraging live-in hunks to cheer them up, will be immediately zapped by the management.
