Are Women Fatter these days?

It's a known fact that all people (not just women) are, on average, fatter these days. 

But, a group of British researchers say that women have gained weight over the last forty years for this, rather sexist, reason. 

Do you agree? 

The cause of weight gain among women in the last half-century? 
A team of British researchers says its because we're less likely to be vacuuming and sweeping the floors. 

Sixty years ago, the average woman had a 28-inch waist (really?) and apparently burned 1,000 calories a day doing housework. Today? The average waistline is about 34 inches. Naturally, the researchers say that it was the housework that kept us slim! (What a concept, right?!)
“When you think of the time that women had to spend cleaning and cooking, life is so much easier now - although obviously that has contributed to the bigger waistlines,” one of the researchers said to the Mirror. 

Hmmm..
