I think it is interesting that I used to be a baby. I bet if we dig into your past, we will find that you used to be a baby, too. There is a Netflix program called "Babies". The first part shows researchers trying to learn more about a baby's impulse to stand up and walk on just two feet. Clearly, bipedalism matters in human life. Hardly anyone moves only on all fours and anyone who did would be considered hurt, joking, maybe handicapped.
Standing on just two feet and having our hands free to do ten thousand other things helps us do things we want to do. The pride and the joy that toddlers show in the Babies program as they find they can indeed plant one foot out there and shift their weight to that foot, leaving the other foot free to do likewise brings joy to watchers and some tears to the eye.
Last night, we moved to another program on Netflix called "The surgeon's cut". The first episode is about a surgeon who lives in London. He was born on Cyprus and is a pioneer thinker about various troubles that mothers carrying babies inside them can have. Prof. Kypros Nicolaides is shown using a procedure he invented to help fetus twins. Sometimes, the blood supply for the growing fetuses goes to the babies unevenly and one grows but the other fades. Eventually, the lesser one dies and then the blood system can ship unhelpful bits to the healthy one and it can die, too.
Nicolaides can perform surgery that separates the blood supplies so that both grow. The program makes clear that the babies don't always survive but the operation, which has to be performed on the mother awake and without anesthesia, often helps one or both live.
The program ends with the information that Nicolaides has developed blood cancer and might not live much longer. It also gives the viewer a chance to see and hear two 27 year old twin men who are alive because of his operation.
