I would say 26 or older. The brain isn’t fully developed until you’re 25 so your decision making skills are not fully developed yet either. The consequences massively out weigh the cost for most people since other jobs and communities won’t touch you with a ten foot poll if you change your mind and want to do something else. And you can only do that can of work when you’re young and attractive so it is temporary. The pay isn’t as great as it seems & it’s super dangerous even if it’s just online.
