Roger Bannister is a (athlete) motivating personality who has proved every thing is a Mental Block and nothing is unachieved if there is a Will. He was a man with mental toughness & perseverance. So what is most special about this man?
There are two things.
1.)  When there was a medical theory going rounds that a person (human being) cannot run a mile within 4 minutes as human body can’t support such an act. He proved those medical theories as wrong.
2.)Â Â He failed on many attempts and with lots of determination he has achieved his feat finally.
Today his record was broken by many but he has to be credited for breaking the theory and did something that every thought was not possible.
