How long has it been since Cain Velasquez last defended his heavyweight title?

Georges St. Pierre was Ultimate Fighting Championship (UFC) welterweight champion, Wanderlei Silva still had a job, Daniel Cormier was competing at heavyweight, and there was no such thing as a UFC women's strawweight division.

My, how times have changed.

What hasn't changed is how frequently Velasquez gets injured, something UFC President Dana White attributes to American Kickboxing Academy (AKA), a "stone age gym" that needs to be educated on how to train fighters without hurting them.

White elaborates to Setanta Sports (via MMA Fighting):

"Some of the camps are still in the stone age and need to be brought up to date. AKA is one of those places. You've got Cain Velasquez, our heavyweight champion, who's always hurt. Those guys go to war every day. He's training for a fight and he's going to war with Daniel Cormier every day. That's not how it's done. Not anymore. We need to educate a lot more."

Knowledge is power!

Velasquez (13-1) is once again set to defend his 265-pound strap -- we hope -- against interim titleholder Fabricio Werdum in the UFC 188 pay-per-view (PPV) main event, scheduled for June 13, 2015 inside Arena Mexico in Mexico City, Mexico.

The last time they tried that ... well, see above.

This is not the first time White has come down hard on a fighter's gym. When Julianna Pena blew out her knee in early 2014, the promotion president lambasted Sikjitsu as a "disgusting" gym that had no business training the "Venezuelan Vixen."

How about it, fight fans, is overhauling the top MMA gyms the key to reducing injuries?
