Well, everyone can't be right in this thread. Why should there be so many differences for those not at the top?
Not everyone is right because there is denial, deception and lies. Who wants to admit that it takes a walking pharmacy to look like a pro bodybuilder.
The protocols followed at the top of any field in life are always the same with very little differences but you think a boxer trains and lives differently then another boxer? or a Hockey player, all the same in any field.
Being creative and inventing a new wheel does not work.
