You can drive anywhere without difficulty.

You can be in crowded rooms and not be overwhelmed.

You can go to stores with florescent lights and not need to wear sunglasses (even at night).

You don't have to be concerned about what you eat for fear it will cause you to retain water you simply can't get off.

You don't have to be reminded by your own self that despite the best elixir of meds, you are not 100%, nor do any of them perfectly fix your ailments.

You don't have to seriously consider never having children for fear of passing on your genes (which go far back on both sides of the tree).

You're ignorant of what it feels like to not want to die, per se, but to simply no longer live your life.
