If Wlad tried to grow a tache today it would no doubt be some weak pencil thin jobbie that would routinely require reapplication with PED infused moustache adhesive. Modern athletes simply lack the raw manliness to grow a decent handlebar. Even in Shavers's day truly top level moustaches were becoming increasingly, ahem, thin on the ground. This can be proven by looking at the sales of moustache wax and men's facial grooming products in the inner city urban populations over the last forty years. Of course Norton was a throwback in this department, which is why I rate him so highly.
Norton famously had confidence issues, he read self help books, sparred LHW’s, wouldn’t look guys in the eyes and had a hypnotist.
