Totally agree with the OP. I mean think about it when do you ever see a hairy swimmer? A split second can mean a lot in that sport. Hair can slow you down.
How come most basketball players are bald? I don’t think it’s because they’re all losing their hair. It’s cooler to run up and down the court,
Full heads of hair can slow down Ivory per say a split second which can be the difference to hitting the holes. It also as the OP eludes to makes him easier to tackle
