Not inventing anything.

Northeast US:

Office hours: 9-6pm -> 9 hours (yes, includes "lunch" where people get a sandwich and eat it at the desk) Note that many people work longer, till 7pm or 8pm (startups, etc). Many people need 2 jobs to pay the bills.

Average commute time: 45 mins (you can google it) x 2 E-mail checking/responding at home after the kids go to bed: 1 hr

Total: 11.5 hrs easily (or more if you want to climb the corporate ladder)

So market-browsing/cooking is not your thing - that's fine. But let me just note that we invented all these life "efficiencies" - and are less and less happy (loneliness, drugs, etc).

What's the point?
