Flippy

This is very interesting. I am writing a fanfic about what happened to the mane 6 when they grew up and I had to come up with a reasonable age so as to establish what would be reasonable for them to happen in the future and when. I also assumed their ages correspond to human ages, for simplicity, rather than coming up with a 1 human year=X pony years that wouldn't work anyway because biology doesn't work like that. Anyway, unlike you, I didn't do any research and just based myself in what maturity and stages of life they are, and I too came to the conclusion that they're young adults. I too took into account that they live on their own and have jobs, but aren't mature. I didn't come up with ages for each of them, but rather assumed they were all around 22. I did mention that Rarity and Applejack were one year older than Pinkie, but that was more for the effect of a scene than anything, although it did make sense . I might take your ages and make use them for reference tho.
