Everybody is like you in some way or other but in a BJJ gym, for example, you will be forced to engage with people of different genders, ages, political affiliations, religious beliefs, intensity, IQ, toughness, education. I do not discount the diversity of the military - if service is mandatory - but in civilian life a BJJ gym might be the most practical analogue.
