Not sure how being overpriced helps their business model back then it was affordable and quick. What is going on?

He smell of Chinese food, has he eaten food? Will he ill?

When I was a kid, summer vacation felt like it lasted forever. Now months seem to fly by, and sometimes I can't believe how quickly the year is passing.

Is there an actual psychological reason for this, or is it just because our daily lives become more repetitive as we get older?

I've noticed that airplane windows often have a tiny hole near the bottom of the inner pane.

What's its actual purpose? Is it related to cabin pressure, condensation, or something else?

I'd be interested in the technical explanation of how it works

Every time someone finishes a shower the sink makes this low gurgling sound for about thirty seconds. It only happens in that bathroom, and the toilet and tub still drain fine. I tried running the faucet for a minute afterward and the noise stops, but it always comes back the next day. The house is about twenty years old, and nothing else seems clogged. I am trying to decide if this is something I should just keep ignoring or if it is worth calling a plumber before it turns into a bigger mess.

I’ve noticed that airplane windows are almost always rounded or oval-shaped rather than square. At first, it seems like a design choice, but there is actually an important engineering reason behind it.

Why would square windows be a problem on an airplane, and how does the rounded shape make flying safer?

I’m curious about the science behind this design and whether the shape also has any advantages in terms of weight, manufacturing, or aerodynamics.

Here's something I've been thinking about lately.

If someone does the right thing only because they want recognition, avoid punishment, or gain something in return, does that still make them a good person?

How would you distinguish genuine kindness from behavior motivated by personal benefit?

My car makes a short rattling sound for a couple seconds when I start it in the morning, then it goes away. A dashboard light is not on, and everything else seems normal. I had it looked at a month ago for an oil change and nothing was mentioned. It is not very loud, but it feels like it might be a belt or something loose. I just want to know if this is a common thing or if it needs a mechanic soon. Any thoughts?

Applies to soda cans, beans, soup, or any type of food/drink really. Question stemming from the ickiness related to transport, storage, and handling.
