TEDtalks, the path to scoring A

I came across this site some time ago, TEDtalks. It's really interesting, featuring talks ranging from science to politics, from environment to motivational. During my brother's prelims last year, i recommended him a couple of talks to listen to, for the topics he was sourcing information for his GP (that boy likes to pick questions to study). And i told him, this site is good. Willing or not, it's up to him to search and listen for himself any other talks that may come up now and then. Well, though he is really quite a slacker most of the time, he is smart enough to know when he is required to put in the effort. I noticed that he took the initiative to search for himself, and listened to quite a number of talks, that he turned around to recommend me some talks to listen to instead! And i'm so glad he did that. Coz i think it benefitted him to some extent for his general paper. Thanks TEDtalks. ^_^
