There are a couple of things that I always appreciate here.
One is the swirl of water vapor in the cabin of airplanes. We fly to Ho Chi Minh monthly, so we have logged a lot of flying miles. And usually, as the plane begins to taxi to the runway, the vents are opened to start air circulating in the cabin, and the humid air from outside comes swirling into the cooler cabin and we suddenly have lovely twirling clouds inside the plane. I enjoy watching the patterns they create in the air. Science is a lovely thing.
Another thing I appreciate is the flexibility and power demonstrate in the Asian squat. Here is a photo of a man, who with his young teenage son, was working at his car and motorbike washing station.
Note the amazing flexibility demonstrated by the angle of his ankle joint. That looks like a 60 degree angle to me with the heel firmly on the ground . That means wonderfully flexible hamstrings. He subsequently made that angle even smaller when he leaned forward, putting his shoulders forward of his knees. Wow. You try it.
And people go from this position to standing up in one smooth movement, totally powered by leg muscles. That's amazing leg strength.
I am always impressed by that flexibility and strength that seems so every-day to them.
