I honestly feel that there is no plan planning for this scenario.
When that time comes, I will just act on impulse. Just do WHATEVER you feel like doing. After all, everything will cease to exist for you very soon.
I would most likely spend it telling my family and friends how much I love them......but it would be good to do one more fun thing, like go to an amusement park, just to end it with a bang, so to speak!!!! :)
