@leadermilk,
No one cares how old anyone else at university - or college - is.
People have their own business to take care of.
Some people start early.
Others return / start as mature students.
They don't care about anyone else's age.
They don't care.
My mother's best friend started university when her husband retired. She was 68 when she got her BA.
No one cared about her age. They were busy with their studies and were only interested in her because she was a good lab and study partner.
I completed a number of university programs in my 30's and 40's. No one cared about my age. They cared about how we could work/study together.
