Making a sandwich involves sourcing the ingredients - time. Then making and packing the sandwich - time.

It makes more sense to pay someone to do that for you if you value the time it takes to do all of the above more than you value the cost of a sandwich.

This is a silly thread.

> Besides, give me one piece of scientific evidence that can prove time actually = money

It's a folk saying, not a mathematical equivalence or a physical law. It describes opportunity cost in an intuitive, but non-rigorous, way. Assuming that there are a set of actions available to me which provide different forms and degrees of benefit to me, my time is most profitably spent on the actions that provide me the greatest benefit.

> Yeah, I bet you save heaps of time by not having food with you and having to go buy it.

Yes? I could go to the office canteen if I didn't want to walk around the corner. Most of the time I do though. (And making sandwiches at home means you still have to buy and store the ingredients).

> Besides, give me one piece of scientific evidence that can prove time actually = money, do you think that staying at work till 5pm every day provides value just because you're in the office? I doubt it.

It gets me paid. It gets me paid more than I'd be paid to make a sandwich. If I could switch to a 28-hour work week and get paid the same hourly rate then I would, and maybe then I'd have enough free time to make my own sandwiches (though probably not, tbh, making sandwiches is less fun than programming). But that's not easy.
