I was referring to this section:

Did you know that you also won’t die from:Lack of physical touch or affectionLack of anyone you can have deep conversations withLack of any change of clothesLack of contact with your childrenHaving a partner who lacks emotional intelligence (sic!)Because nobody has died of lacking any of those things either.

I don't have "research" but it is common sense.

Married people live longer. Babies will die without physical tough. So it follows that men (or anyone) who live without the above necessities won' t hang around for as long.
