In my mental scheme slack is mostly synchronous (people expect a reply, there's a @here thingy to ping everyone, etc) whereas e-mail is asynchronous (people don't expect an immediate reply). You said "asynchronous communication is detrimental to your health". Since asynchronous=email, I read "email is detrimental to your health". I thought you meant the contrary (slack is detrimental to your health -> synchronous communication is detrimental to your health) so I though it was a mistake. Wasn't it?
