I am currently working on a report, which is expected to be in excess of 100 pages.

I have enough material, and if I re-structure it, it will be completed as a report, but it's going to be a long and tedious process.

In the past, I used to be able to work on these tasks while watching music or cartoons, but lately this has been impossible.

I come to be able to do both tasks at the same time.

I think this is evidence that my brain's parallel processing capacity (multitasking) is breaking down.

-----

But you may be able to multitask with content you've already watched.

In my case, "Three Kingdoms" is it.

Already, this content itself is already in the easy listening category for me.

All in all, I work through 95 episodes, about 100 hours of drama, while lazily listening to it.

And, well, sometimes I think about this drama.

"The 'northern expedition' that Zhuge Liang tried many times is, in short, an 'aggression war'"

and

I'm sure that Hou Tong (Shi Yuan), who pretended to be Liu Bei at "Rakuhouha", was prepared to lose his life in his calculation, but that subordinate would have been killed by collateral damage for no reason.

I continue to work with thoughts that "ruin" famous scenes from the Three Kingdoms.
