This is another aspect that hasn't been discussed yet...lots of people don't realize how much you need to save to even have a modest retirement.
My brother is 44, so he's got 20-25 years left. He probably makes $60k or so, and his wife probably as much as he does. I think he's put the bare minimum into his retirement, and definitely has not paid attention to how much he SHOULD put in. My dad mentioned to him that he should strive to get at least $1M in savings by the time he retires. My brother didn't believe him and basically told him it was impossible to save that much money.
I have been thinking more and more about retirement and how much you really need. It scares me, I feel like even a million is not close to enough, it might be 2 or 3 that you need.
