A customer writes in to ask us about what he reads on the Internet about people hitting golf balls. Are these people lying? Determining what distance someone can hit off a tee is impossible to do as every person is different. Looking at someone, you never know how far someone will be able to hit the ball off the tee.
Whether from injury, old age, or some other physical limitation as we get older we cannot hit the ball as long as we once could. I personally have lost considerable club head speed over the last six years due to surgeries that have decreased my arm strength. No one is immune to this fact. While he still hits drives over 290yards, DJ has suffered from decreased clubhead speed as he has progressed into his 30's.
