Young people are always singing: I believe I can fly! So wonderful a dream to the most of us.

While, as the time does fly like a rocket, the young become old, be sick, get involved in some accidents,…… Eventually, our legs seem full of rocks during stepping forward or even can’t stretch or bend easily. Life is restrained to square inches. To walk out of a “cell” to have a deep breath of fresh air, to run and play in the rain like kids, to see and feel the magnificent scenes on the world,…… are the utmost luxury wishes.

What they want, what grandpas & grandmas want, what you and I want is

FREEDOM!
