Wow guys. I know we talk a lot about lifting, and self improvement, and game, and women, but let's not forget about that other core tenet of TRP - having male friends.

Summary: This study from the UK is stark and sad. As you get into middle age, you're 3x more likely to be friendless than you were in your teens.

Also:

While 11 per cent of single men said they had no friends to turn to in a serious situation, that rose to 15 per cent among married men.

Strikingly, married men are also more than twice as likely as men who cohabit unmarried with a partner to say the same, suggesting that marriage itself, rather than being in a long-term relationship, cuts their ties with their friends.

And the effect could be permanent, the findings suggest: even divorce does not increase their overall chances of having close friends they could turn to for help, which remains at 15 per cent.

Lessons: when your buddy texts you and says let's grab a beer - DO IT. Make more of an effort to keep your male relationships intact as you get older. And don't get married.
