Yeah, it's hard to substitute #realwork with #fakework. Fakework is what you do to prepare for realwork or to maintain a certain level of fitness between bouts of realwork (such as when you're snowed in, on a submarine, or stuck working overtime at a desk job).
If you're _only_ doing fakework, but that regularly, you should at least consider rebalancing. Unless you're in training for a weightlifting competition, or undergoing rehabilitation, or something.
It's not that fakework is worthless, but we should always remember that it is merely the means to some productive end.
