Good sleep ability
Some people can sleep less than 5 hours and continue to function normally. This is because of the Tocher gene, because this prime minister could sleep for only 4 hours a night and still feel good. People who have this gene do not only sleep less, but even after 38 hours of sleeplessness, they perform their mental tasks better. But only Thatcher did not have that extraordinary ability, Thomas Edison slept for less than 5 hours.
