“I hear and I forget. I see and I remember. I do and I understand.” a person (or panda?) really do stuff, rather than hear about it or see it. He said it is the reason they travel, and hike and bicycle, instead of watch other people do stuff on television. I think I remember such a thing from my other life. The people were always sitting in front of it and not talking much. They might have doing this thinking thing, but I couldn’t tell.
