This question was originally posted on Quora.com and was answered by Doyen Rainey, Pre-Health Advisor at The University of Texas at Dallas It’s vanishingly rare for someone in their 60’s to apply. Even applicants over 30 are rare. As you can see from the AAMC’s data, the 99th percentile of matriculant age is about 30, meaning that less that 1% of successful applicants were over 30. A 63 year old applying to med school in the US would begin med school at 64, graduate at 68, then start a residency where they’d work up to 80-hour weeks until age 71–75 (depending on specialty). After completing that residency training, they’d become an independently state-licensed doctor…and begin paying back the six-figure med school loans. Several years ago, one of the Texas schools DID accept a gentleman in his sixties, a retired pharmacist, but he dropped out after year 1. I suspect he found that running a marathon of all nighters against very bright 20-year-olds was not much fun at all. Source
