I'm sorry, say what?

So I get a boat load of emails at work each day. The other day I received the following:

So okay dehydration is important. I live in a desert, of course it's important. However...should this be the subject? It had five topics inside and it's not like the others said anything resembling 'not being able to poop=bad, get a colonoscopy!'  Or underwear on the head...do you know the top five signs of dementia?  So... Rather shocking, and unnecessarily so I thought.

 I might have tried to drink more water that day. I can't remember.
