It happens with me alot oftime. Talking of corporate, i am into one of them India..and wheneverthere is any meeting where many share knowlegeable stuff in pitches form presentation i feel sleepy...bullshit...so boring out of it . add onto more, the educational talk are worthless unless and untill you were not into any kind of situation. People learn more from own hit and trial i.e own expereince rather than listening to others.
