One kind of 'popular science' fun facts that is very popular is to show how many of the individuals belonging to a notable group of people that are left handed, often showing a large disproportionally from the rest of the population. (example with Apollo astronauts, but that is a small sample size) This has been asked about presidents and Nobel prize winners etc., But are there any handedness skewing regarding astronauts too? This discussion suggest such a correlation.
As far as I can see, handedness may have a slight impact on the design of control panels and equipment with chiral properties, like scissors. (In the later case calling for a more neutral design in order to maintain uniform productivity.)
