The sickest people I know are the "clean freaks" who have auto sinks and auto soaps in their house, use that hand sanitizer every second of every day. Why? Because they're immune system is shit. It's never exposed to anything so it's never built up an immunity to anything. So when they are exposed to the slightest little bug they immediately get sick, and don't get over it quickly.
