P.S. I am on very strong 4-drugs anti-tuberculosis meds and I am basically so exhausted that I can only sleep continuously (about 20 hours a day) and eat. So I am in sort of state of near delirium, so apologies but the quality of my cognitive state (and thus prose) is highly diminished at the moment. I am posting on this topic because I think it is perhaps the most important thing I can possibly do with the limited moments I have awake. And because I don't have enough energy to do any real work (such as programming).
