Tja, als je de mensheid dan toch al zoveel geld afgetroggeld hebt kun je het net zo goed weer weg gaan geven, loop je ook nog kans dat mensen je aardig gaan vinden...
Bill Gates has whacked in another $5 billion (or it could be $6 billion -reports vary) into his very own home-grown charity.
This is the biggest gift yet made by a living donor. But Gates has a couple of billion dollars to go before his charitable foundation overtakes The Wellcome Trust, the world's largest, with $19.1 billion worth of assets.
The foundation stakes are hotting up, with Bill and Melinda merging the William H Gates and the Gates Learning foundations to form, well, the Bill and Melinda Gates Foundation. Combined assets are $17 billion.
The charitable focus remains on healthcare, and technology in education and libraries. One idea is to create a market for a malaria vaccine that hasn't been developed yet. Shades of Windows 2000, perhaps?
