Is this author serious? I don't consider answering emails, doing laundry, keeping the house clean, paying the bills on time or doing other tasks like going to the bank to be much harder than breathing or tying my shoes in the morning. These are simple necessary tasks. They are done routinely and can be done without much thought or effort. I'm seriously concerned for someone who has this much trouble with these basic parts of life.

Is this a mental disorder? or just laziness to a level I haven't seen?

I agree with the author's choice of title though. If I had to imagine someone who has trouble with such simple tasks, a child is what I imagine.
