Check up before marriage II

So, back in 2006 I wrote about how Kuwait has only (back then) recently considered running medical check-ups before marriage. Ever since, I've been getting hits on this blog.

Medical check-ups. I didn't really look into it. I didn't research it. But I did find this movement interesting. It's interesting to know people now will be able to find out if their partner had AIDS, genetic defects, or any other common disorders that may be passed on.
This begs the question, at the end of the day, does this check up even mean anything? What if you fall for someone, someone that the check up advises you not to marry.
