Yesterday in biology class the "smart-guy" almost got into an argument about how plants acquire energy, with the biology teacher......the botanist with the doctorits. Not saying people don't make mistakes just that you'd be better off arguing about something that someone hasn't spent the greater part of their life researching and writting books about.

'Choose battles you will win and abandon those you will lose'

I think Sun Tzu said something like that.
