Interesting. We are FI. I am RE, and DH still works. His mother has Alzheimer's and lives with us. He is the kind of guy who stays busy. He would go bonkers if he was "cooped up" at home with her. He loves his 9/80 job which is about to become 4/10s, woot! He walks to work and is four years shy of a sweet, stable, Defined Benefit Pension, complete with annual COLA. His job provides amazing healthcare. We have no monthly premiums, no deductibles, and minuscule co-pays. When he hits his target number, we will get a lifetime healthcare allowance and be allowed to stay on the company program, which is worth a lot.
In short, we aren't aiming for five million, but it could easily happen. In which case, we plan on donating a shitload of money to charity. We do a good amount now (about 10%), but as the 'stache grows, we look forward to doing more.
It is most definitely not a race. More of a slow, easy slide into home. Pinch me, I must be dreaming.
