My friend's family owns a street next to a local golf course, there's 4 giant houses on the long-ass street, his grandparents in one, his two aunts/uncles in the other, and his family in the fourth.
His grandparents founded their company.
They all have an indoor pool as well as an outdoor pool, and they have a hot-tub, too. All of that in each of the 4 houses. =/
Why would you even need an indoor pool? I have an outdoor one and a hot-tub already, don't really need much more than that, tbh.
When you look at his house, it looks like they over did it.
Oh, and relating to the topic, his father has a bright yellow Lamborghini. He'd slit both our throats if we tried to drive it, though. No joke.
