I can say first hand , because I have a brother that has done just that for almost 30 years. He is trained in Martial Arts and is an expert marksman. Chuck Norris said a few years ago, he was definitely in the top 10 to 15 martial arts experts in the World . You would never guess that by looking at him he mean lean and very Flexible for his age. I don’t know many people in their 50s that can do the splits!! He CAN. ! He started in military in special forces and was heavily decorated. As a result , learned the intel trade for a few years until a famous singer approached him to be his personal bodyguard. He was offered a sum of money, that he could not turn down. He has traveled the World and most every state in the USA. He always stays in the ( Best ) accommodations, eating at the best restaurants, but always next to this celebrity, while in touch with others by the earpiece he wears. He always travels with this person and directs others located in different areas . He works long hours and coordinates the travel and security plans in advance and while they are in the city of the performances. He is especially on high alert during concerts and one occasion he went for special food for this performer.he was recognized by two NFL linemen who could not believe a 6 ft 1 185 ( white ) guy could be ,( that bad). He ignored them , but they persisted and both grabbed him and ( tried )?to punch and fight him. These 2 NFL players were transferred to the hospital. My brother was never changed , just questioned about the incident. Witnesses corabrated what happen and they viewed the security footage. He was released, but the two lineman missed several games because of their injuries. He has also been loaned to work for high profile Actors and some very well known wealthy individuals. He has told me it’s dangerous, long hours, but you see the world and stay in Hotels , most people only dream about, not to mention all the high profile and famous people that he has met and even more interesting, getting insite into how they live and ( how they really are in private)! He has shared some very interesting stories!!!
