I'm good friends with a 62 yr old who could kick most peoples arse-no matter the age.Ex navy seal.6 2 230.
20 yr olds -exc for the obvious cases in football-- are not that strong yet. A 50 yr old truck driver will kick some college punks arse any day.--
That being said--you are right young punks have no right to be physical with ANYONE over the age of 30--just as a matter of respect. Respect your elders.-Esp since you may get an arse whoopin.
