What do you think Future Retirement homes for Millennials will be like?

I'm imaging senior citizens with iPhone 20s and playing Call of Duty 15 on futuristic consoles. Also there will probably be parties. What do you think the future will hold for retirees?

Just the same as today Old people waiting until they die.

A mansion

IPhone 20s? By the time Millennials retire they will be on like the iPhone 50.

The robots will kill them all

Sounds like fun.
