Apparently sharing a bed with your partner may be bad for your health as another person can restrict just how well you rest, eventually causing/contributing to difficulties such as heart problems in later life.
Would you be happy sleeping apart from your other half (hate that expression)? Like properly having your own bedroom away from them? Seems like nonsense to them, I'd feel like a proper spod having my own room. A spare room that I used from time to time if I was especially knackered maybe but anything else just seems a bit Victor Meldrewish.
AND if you sleep in a different bed to the woman, how the hell are you supposed to poke her with your morning wood? It's balderdash.
