OK so I know this has been asked but I still don’t get it.
Who do humans age faster/slower? (Shown in interstellar for example) Biologically I don’t understand why the body would age faster?

It seems intuitive that time is the same for everyone. 30 mins lunch break is the same in New York as it is in Tokyo or Paris.
Which is true, because we’ve never experienced the conditions where it isn’t true. An experiment carried out over 100 years ago proved that light always travels at the same speed for everyone everywhere.
So you’re at home looking out of the window. The sunlight hits your face at 30 million m/s.
Then you see a superspeed rocket fly by at 10 million m/s, towards the Sun. Obviously if the Sun is reaching you at 30 and he’s heading towards it at 10, then the collision speed must be 40 million m/s. But no; everyone see light at 30 million m/s.
Einstein figured this out because time in the rocket, as you see it, is running slower than yours, so the passengers are aging less.
