FWIW...I agree with Blade about retiring with a big portfolio.
Most everyone on this board is younger that 50. I think what everyone needs to take into account is that getting older is getting more expensive. Especially since safety nets like healthcare, insurance, nursing homes, etc are getting so expensive.
These are things that are really going to chew up a portfolio once retired.
Instead of retiring, I plan to work the minimum amount i need to get benefits. Work keeps my mind sharp, I like the people, and when the next orthopedic procedure comes along that i need, i will hopefully have some sort of healthcare plan.
