my friend is a killing machine but he's afraid of social interaction

[mr take your gf]

my friend is a fucking specimen he's 193cm 98kg
black belt judo
purple belt jujitsu
8 years of boxing
he's afraid of social interaction when I asked him why he told me he don't know what to respond when people talk to him and that he wish if he was born in the middle age
is he an introvert or is that social anxiety?
