Shakespeare had it right when he offered poetic praise to the Creator for the marvellous complexity of nature. Hamlet’s speech has always been a favourite.
Recently I had surgery on a vein in my left leg. This required wearing a compression stocking for several weeks 24/7 which was an uncomfortable pressure. In the follow up appointment with the surgeon he gave me a date to take it off.
When I removed it I immediately had a strong sense not just of relief, but how marvellous is the complexity of the human leg. It sounds obvious when you realize how dependent we are on the exact functioning of the muscles, bones, arteries, and veins, etc to stand, let alone walk.
