I'm 35, I've had major shoulder surgery on my left shoulder to reattach my bicep, two major back surgeries including a multi-level spinal fusion, and by the end of June will have missed 12 of the last 18 months of work due to injury/surgery. Both ankles are permanently messed up due to constant sprains and breaks, my left knee randomly doesn't work right due to a dislocation, I have frequent migraines, and unfortunately due to all the injuries and surgeries I've put on some extra weight. Not to mention having autoimmune disease...
Unlike inside, I at least look my age on the outside (mostly due to a smattering of gray hair, otherwise I would look a bit younger than my age).
