Cheers for the offer @lilbud. It's not so much a matter of ability, as it is of time.
I wake up, go to work, get home, make dinner, put the kid in the bath, put the kid to bed, spend time with the wife, go to bed, repeat. On weekends, replace 'work' with 'house work' (washing, mowing, dishes, cleaning etc). The only time I have to myself is from between 10pm - midnight, so I can either go to bed at a decent time, or do something for myself for a couple of hours. Usually I just read to unwind/relax.
