premise: Sir David John White, {'1': ", '2': ", '3': ", '4': "} (born 2 February 1940), better known by his stage name David Jason, is an English actor and comedian. He is perhaps best known for his portrayals of Derek "Del Boy" Trotter in the BBC comedy series "Only Fools and Horses", and Detective Inspector Jack Frost in the ITV crime drama "A Touch of Frost".
hypothesis: Sir David John White is currently 20 years old.
reason: It's definitely incorrect because he was born in 1940. I think it's difficult for the system because it involves calculating and comparing ages.
