why does time seem to go so fast in the morning before i go to work? i only sit there on the couch doing nothing. yet when i get to work, time seems to drag all day?
I get up around 6 am, then I have 2 hours before work. It's like I'll look at the clock and it's lets say, 6:40. Then what feels like a few minutes later I'll look again and it's 7:05.

why do breakers on a beach look like they aren't moving when viewed from an airplane in flight at high altitude?
This one has been bugging me for years,and I was hoping someone here could explain this. The light from the waves is obviously moving fast enough, so why is it I can see the lines of the breakers, but they appear stationary?

why aren't obese people's muscles stronger than average, considering they carry around so much weight every day?
I am sure there's some wrong with my thinking, and I'd like to understand what. I think it is a fact that the more you exercise a muscle, the stronger it becomes. Let's assume we have one obese person, and one person of healthy weight. Both of them walk 1h per day over the same distance. Since the obese person carries ...

how can video games be played from a cassette tape?
I'm talking about old 80s and 90s computers that played games (and possibly run other programs I guess) via tapes that looked like audio cassette tapes. How does that work? If you want to listen to an audio tape from the start you have to rewind it, not so if you lose a game on a tape and have to restart it.
