(Cover) - EN Showbiz - Keanu Reeves has ridiculed critics who say he never smiles.

The 46-year-old is best known for his role in the Matrix trilogy, where he played lauded saviour Neo. The actor - parodied for his deadpan persona in films - has turned on his detractors who insist hes always melancholy, instead questioning how he should present himself for best first impressions.

How do I live with any happiness? Im not living if I dont have a Golden Retriever! I see articles all over about what is the new happiness. Whats the happiness length? How many units of happiness does it take? Well... you have to have at least six portions of four units of happiness in each cycle, he laughed to Elle.

Keanu added he feels fortunate to have experienced his rush of fame when celebrity worship wasnt as prominent as it is now. He often wonders how todays new stars cope with the almost continuous intrusion into their private lives.

I didnt experience it like they do. I dont know if its an obsession with celebrity, or because theres more output opportunities for it. In 1992, there werent so many. Twitter, all that stuff, is definitely a new world. Their privacy is a lot less, he said. (C) Cover Media
