I'd like to share an inspiring short article which is translated by a friend from German to English.
The bumble bees
For the people who say " I can't" to restain themselves (including myself!), they should think of the bumble bees .
The bumble-bee does has a wingsize of 0,7 square centimeter but a weight of 1,2g.
According the theory of aerodynamics, the bumble bees are incapable to fly with its weight and the wing size.
But the bumble-bees don't know that it's impossible.
and they simply fly!!
