I just got through tape 1 side A, and I found Master Lin's explanation of Yin & Yang fascinating. It explains the 'idea' (is that the right word?) of 'strong, dumb' people and 'smart, weak' people. It also may explain why untrained muscles hurt when exercising...they are unaccustomed to the excess of Yang...

Master Lin is definitely right when he says that with computers, etc. we build an excess of Yin!

On to 1b!
