Old people likes to say, I eat/walk/whatever more than you. But if they don't learn new things, their knowledge still the same for whole life, right? That's why I fed up with management (aka old people) who thinks they know every thing but ended, still ask me why I am good in this and that. Cause I willing to learn, practice, experience etc and not sits there to see how the world moves. When I talk to my mum over the phone, she also agreed on what I said some time as technology nowadays are totally different from their time. But some time, we still have to take advise (some) from old people, to respect them mah.
