Well I am 33 years old and having been a bouncer for a long time. At 6'4 and 265 I have plenty of friends that know I can handle there needs. I am a regional sales market manager for a large company and everyone that knows me knows I can talk my way into or out of most situations. I am called to help do security at concerts and have provided security for large parties because people know I can not only physically handle situations if needed I can talk and diffuse situations as necessary. I am married with 2 kids and am long past the partying stages in my life. These side jobs pay very well. I am not or have never been in law enforcement or worked for a security agency. I could probably do so very easily.
Not everyone over 30 that does this needs to grow up.
