The world's second richest person Bill Gates, who commands a personal wealth of $96 billion, recently disclosed that his house has a trampoline room, admitting that it \u201cseems kind of over the top but my kids love using it to work off their excess energy.\u201d The Microsoft founder revealed this during his ''Ask Me Anything'' session on Reddit on Monday when a user asked, "What's the most \u2018treat yo self\u2019 rich guy thing that you do?" Two big-ticket items came to his mind. \u201cI have a nice house. It includes a trampoline room,\u201d he wrote, admitting that it \u201cseems kind of over the top but my kids love using it to work off their excess energy.\u201d And \u201cthe other thing is that I sometimes use [is] a private jet,\u201d Gates continued. \u201cIt does help me do my Foundation work but again it is a very privileged thing to have.\u201d Apart from the trampoline room, his over $60-million mansion is equipped with a library, an in-house theatre, and a 60-foot pool fitted with an underwater music system. Gates, who helps run the world's largest private foundation with his wife Melinda, held the position of Microsoft CEO until 2000. One of the Harvard dropouts among Top Five, Gates is by far the only billionaire to splurge on a private plane. Gates was also asked if being a billionaire has made him happier than if he were just a middle-class person. Without beating around the bush, he wrote, "Yes. I don't have to think about health costs or college costs. Being free from worry about financial things is a real blessing." He added, "Of course you don't need a billion to get to that point. We do need to reduce the cost growth in these areas so they are accessible to everyone."
