Gaining knowledge, improving brain power, personal accomplishment, new horizons, making new friends and acquaintances, sharing ideas and thoughts, benefitting from other's experience, opening many more doors, when is it ever too late for any of these? Pursuing an education enhances all of these and so much more. I recommend regardless of age, it simply should not be a factor. If all goes well you will continue to age, with or without an education. In my case I could turn 45 without an education or turn 45 with an education. Either way I turned 45. Thankfully I chose to do so with an education, and I have not a single regret, quite the opposite.
