I think It depends on the individual person. Competitively, I think a lot retire before college or in their twenties (note that a lot of adults don’t start until their kids do though). One of my teachers is nineteen and retired from competing before college- all she does is teach now. I know a lot of teachers are actually “oldish”. The sounder of my school is in his 50’s, there’s a girl on here who said her teacher was something around 70. Micheal Flately is 52 So really, it’s basically all dependent on the dancer and how he/she feels.
