August 13th is observed as International left handers day.
The reason for left or right handed is quiet undecided.
Recent studies revealed that it may be linked to gene activity in the spinal cord.
More men are left handed compared to women.
Advantage:-
Left handers are faster in doing multi tasks ,as both the hemisphere's in the brain communicate faster.
Recovery from stroke, brain related injuries are faster in them.
