If there's anyone who knows just what kind of joy and displeasure combat sports can bring you, it's former professional boxing champion, Mike Tyson.
"Iron Mike" has experienced the highest of the highs and lowest of the lows during his professional sports career.
From being the youngest fighter to ever capture the heavyweight title to getting knocked out by James "Buster" Douglas -- a man no one expected to survive more than a few rounds against the bruiser -- Mike has been there, done that.
That said, Tyson recently spoke to TMZ Sports to offer some encouraging words for Ronda Rousey after she dropped a bombshell that she briefly contemplated suicide after getting knocked out by Holly Holm.
