Alright, instead of speculation, I'll tell you what actually happens on my normal day.

5:30 - Get up
6:15 - Leave for work
7:00 - Get there
3:30 - Come home
4:15 - Arrive home

Factor in the fact that most of this time, my kids (if I had any) would be in school, and this doesn't look that bad.

An hour and a half to work? Blechh, and I thought my drive was bad.... Also, I don't sleep 8 hours a day (that'd be real nice, tho - I normally get in about 6-7 hours)
Ok, first your job starts very early in the morning, I presumed that the earlist you would work is 8. Second I thougt you said your commute was an hour and half some time so that is my bad. Third you work 8 hours 30 minutes, witch means you are already working OT.

Fourth kids don't go to school for the whole day, until they are at least 7. What are you going to do then? Your wife (if not devorcied) will want to work also. Put them in a day care center. I hate those things, they are way to scheduled for a 2 year old. Also to much importance is placed on being a super genius now instead of letting them be kids.

Fivth even if you never sleep again your kids still shoud be allowd to sleep.

One final note: If you never have kids none of what I said matters.
