This is just the basic equation of actuarial science.I'm also once interested in this core but after consideration, I finally moved down and go for business. Going for AS, the degree is nothing basically. It's just a basic concept how & what AS do. The degree proves nothing. You have to go for 9 professional papers only to be a fully qualified actuary. It's no joke, from what I researched. It requires at least 6 years? for moderation level.
Age 22 finish degree + 6 year to finish paper = 28 yo... And Hei! You still got so much commitment, GF / work / car payment / wedding or maybe even got son. So basically depends how discipline you are! If you're not a self-control person. Please don't think, I think you would be old enough before you completed all of it.
Here are some links about AS and I hope you do spent hours on it because I can ensure that it can answer all your questions. Don't be lazy cause I also spent days doing research when I was once interested.

If you don't design your own life plan, chances are you'll fall into someone else's plan. And guess what they have planned for you? Not much.
