A new study has emerged saying that women way more on average today than they did 30-40 years ago because they don't do as much housework.

Now, this is obviously totally sexist, obviously.  However, the study says that because women are now out in the work force and not at home as much that they're are burning up to 400 calories less a day.

Back in the 60's and 70's women did around 30 hours a week of housework. Now they do around 13. Meaning they're burning less calories.

Now that more women are working they're more likely to take some time to relax when they're at home instead of doing housework.
