A man who had nothing but everything

Have you ever come across a man who has no house,no family,nobody to think and care about but has got enough money to buy an air-craft.
People like us who have everything find it strange and difficult.Its weird but true.
He is like a nomad who travels round the world.He never carries a suitcase though.What he does is hard to describe but he is the most wanted person by business tycoons around the globe.
And this one is the strangest for me..nobody has seen him smiling till date.
Isn't it interesting?
Have a look at this article and you will understand what I am talking about.
