It doesn't make a difference if this middle aged male is subpar. Hubbard should never have been there. He took an opportunity from a young woman who did deserve to be there.
In some respects it's just as much of a travesty that he is twice their age, unfit and with terrible technique. Makes a mockery of what the Olympics are supposed to be.
For anyone who thinks it doesn't matter because he didn't win needs to remember that this sets precedent so the next country to send a male person into the female weightlifting competition (or any other sports category) might send someone who is 20 years old and at the pinnacle of male bodied fitness.
