I'm very good at combat sports like martial arts, fencing, kendo, marksmanship, archery. I've won a lot of tournaments, and enjoy competing - especially when competing with myself because for me it is about self improvement more than anything.
My dad is an ISTP, and also a kung fu instructor, so I was put into the lifestyle at age 5. It's something I've always stuck with as an enthusiastic hobby. I'm a fan of doing individual performance combat sports, but I have to say I generally don't watch them unless I want to learn something from the contestants.
Because of this, I've done fairly well when I have played team sports, but it's not really my bag. I'm not interested in playing them, and even less interested in watching them. I'll play a game here and there, if I have friends or family who need an extra player, but it's never something I seek out, and I doubt I could name more than a dozen professional teams of any given sport.
I've read that all of this is very typical of males who have an inferior Se. We either go this route or become extreme pacifists, which is also ironic because my favorite martial arts are now aikido and tai chi because they are so wonderfully peaceful and passive. I doubt anything is more of both options.
