I digress from the blogs on
Sleep to answer this question and will soon get back to how sleep matters.
The news says that while more females than males catch this coronavirus, a larger percentage of males die. What’s that about?
In a word, gender differences in
immune system function. Do you remember studying about your genome and chromosomes
in high school or college? If not, here is a bit of biology. If yes, it’s just
a refresher. The average female has 23 pairs of chromosomes (for a total of 46)
that she got from her biological parents. One of each pair coming from her
mother and one of each pair coming from her father. You might say that 22 pairs
are regular, and one pair are sex chromosomes. Since females have two “X”
chromosomes, the child will always get an “X” from its mother.
More tomorrow.
