DNA at home?
So we're leaping already from Dad's running DNA tests on their kids to see if they're the biological father, and therefore liable to maintenance?
Instead, kids will be running tests on their parents to see if they are adopted (or otherwise not direct offspring), so they can tell their parent's they won't do domestic chores unless they're paid a salary?
Tom, If Katy comes for you with that cotton swab, be afraid - be VERY afraid!
