2. Buddhist Monks
These people are known for quite a lot of superpower-like abilities. For instance, in the 1980s, Harvard Professor Herbert Benson went with his teammates to do a little research among Buddhist Monks and they found that these people can change the temperature of their fingers and toes by 17 degrees. The very same Monks are known to live winter nights 15000 feet high in the Himalayas. They can also dry wet cold bedsheets using nothing but body heat. How they do it, is still a mystery. There are also meditators in India who can lower their metabolism by 65% which allows them to survive without eating much. Meditating can indeed be the key to unlocking hidden superpowers among men.
