I'm not talking just about exercise, eating right, etc. I'm talking about things you can't prevent...like certain diseases you may have.
With so many foreigners coming into the more sanitized western world, "pure" people are less.
I'm not sure if any of you ever bothered to take a blood test or biopsy, but you'd be surprised by what you may have. There are so many different diseases out there that can be contracted and such that it's amazing that there's a few "clean" people left.
I know 99.9% of you reading this are pretty young, so what affects you now worries you little. I'm 21, I always am thinking about the future and how I may die. I don't want to die from cancer or some stupid disease I didn't bother to check. Maybe it's not important how we die, since we'll all die anyways...but a good exit never hurt anyone.
But eh. My final thoughts are that, everyone should go take a blood test now and see what they're infected with. Maybe I'm spooked out about how I'll die, but technology almost always never catches up with disease unless we're still alive 100000 years into the future.
