LOL , getting older sucks , but you sound like you know what to do and as importantly , know what to expect . Thats more than most people do . That guy in the video is a Spetsnaz , he trains Russian special forces units . The guy is an animal . I dont mean that in a negative way , the guy is big , and ruthless ………..one of those people that you would have to shoot from a distance , because if he gets close to you ……..your screwed !!!! no matter what you do or know .
