Lolenga Mock, who turns 47 in April, considers retirement and wants farewell bout against strong opponent. Mock is fighting as a pro since 1991, and he was stopped only by David Haye, whom he dropped too. He's 42-16-1 with 13 KOs “My advice to young fighters is to avoid drinking and smoking, stay focused, humble and positive. Surround yourself with good people and good energy – people you trust with your heart. Never give up on your dreams!” - said Mock
