Albert Einstein Rode A Bike

I've posted this picture before...I just love it, he looks so do many people when they are on a bike. Anyhow I came across these following quotes and thought I'd re-post the photo.

Life is like riding a bicycle - in order to keep your balance, you must keep moving.
~Albert Einstein

I thought of that while riding my bike.
~Albert Einstein, on the Theory of Relativity
