SUBREDDIT: r/AskReddit
TITLE: 'Eyo reddit. I'm wondering what I should do with my life.
POST: Hello Reddit. I'm a 17 years old guy, and I've been seriously considering what I want to do for the rest of my life...

I always, as a child, thought of being something like a physicist, or a civil engineer. But hell... I can't imagine myself working for the rest of my life behind a desk. I don't mind having to study for my career, as I'm a pretty smart guy (I'm great with numbers). 

I was thinking on becoming a pilot, and it's a plan, but I want to have more options to pick from.

Anyways, I love human anatomy and calculations/numbers, those are my best traits academically. 
I want a job that, even if gives a low pay... I just want to have an active job, where I have to interact with other people alot, can meet new people. Being able to travel would be a major plus. I just don't want to get stressed out, work too much and see my stomach grow with time. 

What would you recommend me to do?
TL;DR: 
I want an active job that might let me have a normal physical activity level, make me interact with people and traveling would be a major plus. What do?
