74 years
Obviously many of you bullshitted your answers to the questions. In 30 years when I'm surrounded by a harem of beautiful half naked women feeding me grapes, many of you who put "90+" will already be long gone.
3/4 of those of you who do make it to 90+ will be bed ridden somewhere in a hospital forgotten by your family, riddled with bed sores ripping through your old feeble bodies.
