You don't have a clue do you - abstract labour is not made abstract labour through mental acts of abstraction - that is a fundamental point of Marx's Real Abstraction (which you clearly don't understand) - it's not a mental process, but a real process, that market exchange and the law of value carries out. The abstraction is "real" because it is not a mental abstraction, but one occurring in reality, one that reduces various disparate acts of concrete labour to abstract via market mechanisms and the imposition of the law of value
The process of abstraction is necessarily mental, twit. Unless you'd care to show me what a material act of abstraction looks like?
Perhaps you mean that this mental process has material results?
So you too believe that shitting and sleeping (two activities that help to ensure labour power is in a sufficient state to be sold on the market to capital) is abstract labour - god help us - and again abstract labour is not something that comes about through a mental abstraction. I'd advise you not to use terms that you haven't properly understood if you want to continue posting on this or other threads.
There really isn't much point is asserting that I am ignorant, you know I am not.
What do you think labor-power is? It isn't limited to acts of labor carried out in the process of production is it?
Or do you think that it is? Let's dispose of that illusion first if so.
