i would go for the lawyer/political person
because for them you need to study a long time
but for massage (which btw isn't easy - you have to memorize shit like all the bones and muscles in the body) you can study when your older
I have a friend who did it after he moved down to Australia because he couldn't continue his old job (teacher)
but its your life and sometimes you just want to make the most out of life away from those musky books, so (ignore the cheesiness of this) look deep in your heart and decide from their.
Words of advice - listen to people a tad older then you going through it
don't ask if its hard - ask if its worth it.
