Hm I guess I will know for sure in 30 years, but it will be expensive if I pay for private, Medicare maybe depending on where I am at in life or the state of the country.

I try to save as much as possible, I meet my companies 401k match plus 4% to Roth IRA (obviously because it is after taxed money) I buy bulk a lot as well so my hope is I can save enough to cover all expenses. That being said I am currently single and have no kids so I have the luxary of having few expenses
