My Gran was a fiesty strong willed bloody legend of a woman, she COULDN'T work when she got married (hence she waited until she was 36 before agreeing to marry my Grandad, so she could work) but by heck she threw herself into domesticity.
Her day to day life was in my modern opinion filled with pointless chore... she SCRUBBED the doorstep and path every morning, same with the kitchen floor, changed bedclothes 2-3 times a week and remained very trim. I think she was actually bored shitless, and was pretty unfulfilled, and very fit.
I am trying to attain some kind of balance between the two, firstly because the house doesn't clean itself unfortunately and I like a relatively clean house, it's good exercise, but I don't have time or desire to scrub the sodding doorstep each day, and I think DH would be a little horrified if I suddenly developed that interest, he's probably better than me at domesticity.
I was a SHAM for 8 years (quite literally in many ways) and yes, I got fat, and was probably lazier than I ought to have been because I find housework just incredibly unfulfilling, so I spent time with my children colouring in and doing lego (perfectly valid, just rather sedantary) I did used to take the children on long walks, and to the play park, but got TOLD OFF for joining in (aparantly the swings and slides aren't for grown ups - who knew?).
On the other hand, my MIL was massive and her house was spotless, so any link is probably bollocks.
