Facts About Us Southpaws

Being a member of an elite society, I hereby present you with some interesting facts pulled out from the internet about left-handedness.  

• Roughly about 5-15% of the world's human population is left-handed.
• 4 of the 5 original designers of the Macintosh computer were left-handed.
• 1 in 4 Apollo astronauts were left-handed (250% more than the normal level).
• Left-handed drivers are apparently more successful at learning to drive than right handed people. As many as 57% of left handers passed their driving test first time compared with only 47% of right handers (a poll for the AA Driving School found).
• Lefties are more prone to have allergies, insomnia, migraines and are 3 times more likely to become alcoholic.
• Most left-handers draw figures facing to the right.
  
• Left-handers adjust more readily to seeing underwater.
• Left-handers excel particularly in tennis, baseball, swimming and fencing.
• Michelangelo, Leonardo Da Vinci, Einstein, Ben Franklin, Bill Gates are some famous lefty geniuses.
• Ronald Reagan, Bill Clinton, George Bush, Barack Obama are lefties presidents I know.

I was hoping to find evidence to support the fact that we are no good at numbers or bad at maths.  Only to find leaning comfort which states left handed people are the only people in their right minds!
