There's a limit on how much housework women can do before it compromises their health, according to new research. But men can basically do UNLIMITED chores and it doesn't make a difference.
It might be because the types of chores men do tend to be more active and physical, which boosts their immunity. And they tend to be less repetitive. For example, fixing stuff around the house is more mentally stimulating than doing the dishes every night. DIY can be fun!
