According to Einstein's theory, clocks slow down while moving at speed, from the observer's pov. So, let's say a person travels at
80% of speed of light and completes a space travel. According to the traveler's watch, it would be 2 years. But it might be 20 years from our prospective. So we will age 20 years, but the traveler would age 2 years. Does that mean physically too? Like, people originally younger than the traveler
would be older than him?

Yes.
All time slows down so that all the chemical reactions sin his body slow as well.

The clock that traverses the most space accumulates the least time. Clocks may only be compared when local (touching).
For 80% lightspeed, sqrt[1-(v^2)/(c^2)], time dilation is 0.6. 2 years traveler time would be 3.33 years observer time. Factor of 10 time dilation requires 99.5% lightspeed.
No matter. The two reference frames have different rates of time passage. When the travelers return and compare, the entire contents of each reference frame will be affected - by the book,

It means everyone not travelling at the same speed as the traveller.
