explain: 1.why china plates are wrapped in paper or straw pieces while packing? 2.why does an engine require more time/kicks to get started during winters? 3.why blood pressure in humans is greater at feet than at brain?

Pls post one query at a time.

 

China wares and glasswares are wrapped in paper or straw pieces while packing so that in the event of fall, impact will take a longer time to reach the glasswares through paper or straw. As a result, the average force exerted on the glasswares is small and chances of their breaking reduce.
