Lots of options actually. If you're healthy, able to concentrate on things for a long time and your brain is sharp then count your blessings.

I once (for only a few weeks, but it felt much longer) had to use medication that made my brain feel like mush, comprehension capabilities were a fraction of normal. Very humbling experience, scared to death of losing my faculties and ending up in that fog for some reason that can't be cured so easily.
