I worked as cabin crew for over 36 years for a major UK airline , retiring last year.
In the 90's when my 3 kids started full time scholl, I re-trained as a swim teacher with the ASA while flying part time (Job Share).
Since retirement last year, i have been a full time student (BA Hons).
Folks love to run cabin crew down, IMHO because they know they would not have the stamina or the innate ability to do the job.
Dont sell yourself short - there is life after flying what ever your age and cabin crew have far more ability than they are ever given credit for !
