I realized that I'll get in trouble if I say, you know, 70% of the training that we do should be in line with our predisposition and 30% should be countercurrent to that.

The more pervasive the countercurrents, the greater the strain of living.

They use a countercurrent exchange just to get all of the oxygen out that water that we can.
