then comes a fresh obsession study: "what happens when Santa Claus is sick?" His influence on the spread of infectious diseases
this paper solemnly uses mathematical models to calculate what happens to Santa Claus who come into contact with a large number of children on Christmas Eve. And set the variable "Santa Claus factor" that represents different degrees of contact. The authors point out that when Santa Claus gets the flu and spreads effectively through contact with children, it leads to a "slight but statistically significant" increase in the size of the flu season. And if Santa Claus has measles and does not have enough vaccine coverage, that is even worse. _ (: astronaut "∠) _

and Christmas on the International Space Station, picture from astronaut Andrew Morgan.
PS: watching the news of Boeing Starliner spacecraft today, it was said that their test flight was supposed to send some Christmas presents to the astronauts during the docking of the International Space Station, but the docking mission failed and failed to deliver _ (: cute "∠) _
