UFC's Andrei Arlovski Shoots Down Retiring at Age 42, 'F*** No!'

UFC star Andrei Arlovski -- the former heavyweight champion -- says he has NO PLANS to retire at age 42 ... and wants to keep bangin' away until he's 45!!!!

Arlovski made his UFC debut at UFC 28 back in 2000 -- 21 YEARS AGO -- and has been fighting consistently ever since.

He won the UFC heavyweight title in 2005 -- and has been in wars with superstars like Francis Ngannou, Stipe Miocic, Frank Mir, Stefan Struve, Alistair Overeem ... you get the picture.

But, Arlovski's coming off a 2nd round loss to 27-year-old Tom Aspinall -- his 10th loss in his last 16 fights -- begging the question ... is he considering hangin' up his gloves???

"Oh, f**k no," Arlovski told us while out shopping in Beverly Hills ... "If the UFC doesn't kick me out, [I'd like to fight] probably like 2, 3 more years. We'll see. Why not?"

In fact, Arlovski is still calling for tough opponents -- "Someone tough and young!"

By the way, since Andrei has fought both Stipe and Ngannou -- we asked for his prediction on who will win that massive heavyweight title fight at UFC 260 later this month.
