No. Non-traditional students are everywhere in our incoming classes: former teachers, engineers, nurses, parents, people who spent a decade in an unrelated career before deciding on medicine. Life experience is a genuine asset in interviews and later on the wards, not something you need to apologize for or explain away.
The real questions are practical, not philosophical. Can you realistically finish your prerequisites, afford the years of reduced income during school, and handle residency's hours in your late 30s or 40s? If the honest answer is yes, the age itself isn't the obstacle people assume it is.
