@Riddler356,
Sometimes genetic history is very important, but do you really, really want to
know everything?
What will you do if you are told you might get illness X sometime in your life?
Worry year after year about something that maybe never happens?
You might get illness X but die from illness Y long before that, becouse you concentrated too much on X and did not check on Y.
Or before you get X there is a cure for it so you did not have to worry.
