From the article:
"He was only able to work at night, when traffic vibrations are at a minimum, with his right arm bound to the arm of his chair with a luggage strap to minimise unwanted movement. He uses a stethoscope to monitor his heart, attempting a stroke of the letter only between beats, when his body is perfectly still. He swims 10,000 metres a day and can slow his heart rate to 30 beats a minute."
Now that my friends is serious dedication...or slight insanity. But either way, I respect it!
