So about 3F: 3F is often quite active, interested in exercising, etc. I think the biggest problem with 3F is body image issues and anything related to body processes. The overreact to any physical stimuli, sounds, touch, taste, etc. And they hate it when someone (like me) rushes things like eating or cooking for instance. Since 3F is processional Physics, cooking and eating, for them is all about the process. So they get pissed when they cook something nice to you and you slide it right into your mouth in one huge bite.
Most of the people in my life are 4F or 2F so nobody ever made a big deal about it. But I find it that all of the few 3F I met in my life complain about how fast I eat and that I don't savour my food. In my defense food is just so tasty that I can't help gobbling it up like I'm starved every time lol. They accuse me of stress-eating or whatever. I just like food damnit!
