In certain countries, do they fire you from your job for becoming old?

An example is a police officer, if you're 40 or older, you might not be strong enough to run after criminals or fight thieves who fight back, so they might fire you because of your age.

Today I went to the bank to deposit a cheque and I notice a bank employee in her early 40s was no longer working there, she had been working there from age 21 to age 38 or 39.

All the employees who worked there looked under the age of 24, other than managers, all had pale skin that you would have to have certain genes or cosmetics to get, and all had 10 out of 10 beauty in their faces and bodies. All were skinnier than your average fashion model. I'm thinking that at least half the employees wore size 0 clothing. This was a Chinese bank in my city where bank tellers must speak Chinese to work there.
