Depends on his financial situation, I got one when I was 23 in medical school. No student loans, saved up cash in hs/college working, college fund basically turned into a mutual fund that is growing every day with monthly contributions.
Now I'm 26, with no debt out of undergrad(in-state + scholarships + living at home) and medical school(college fund paid for this + shared apartment)
"College" fund still has more than 65% of what I had initially turned over to an aggressive mutual fund.
Who knows maybe he has all of this and a house, investments, etc etc etc
Hard to judge on the internet lol.
