Two 秉 elements merged and juxtaposed side-by-side connoting two mandated woody-reaming-with-a-bougie sessions back to back or simultaneously, as something that CANNOT BE DONE (see 棅 for meaning and 凲, 慊 for juxtaposed elements). The administering of TWO MANDATED JOBS CONCURRENTLY will cause HESITATION in both the patient and the medical service provider due to the pain involved, but more so due to the obvious limited effectiveness of a second reaming session immediately following the first. Needless to point out is that a male human has only a single urethra, generally, hence concurrently reaming two CANNOT BE DONE. Furthermore, a medical service provider can only administer treatment to one urethra at a time as well. BEYOND ONE'S ABILITY probably refers to both the patient and the doctor. Official records were maintained of treatments, and some patients might have wanted to increase the official count of treatments performed within a shorter period of time in order to lessen the overall duration of their quarantine at the expense of total incapacitation for a brief time regardless of its ineffectiveness, known today as GAMING THE SYSTEM by violating the spirit but following the letter of the law…doctors do that, too sometimes.
　Scholars explain this as single hand holding two rice stalks as 'unable to do,' nevertheless, practical experience and common sense over the past 400,000 years dictate that in fact it is humanly possible to hold two rice plants (禾) in one hand concurrently with ease, and that even in the good old days, uneducated serfs performed this purportedly impossible feat, and more often every day during harvest time. If they didn't, it was likely that co-workers would whack them for being lazy. People often do two things at the same time, but there are certain tasks that no one can do simultaneously.
　As a footnote, some members have suggested CUM as something two cannot accomplish simultaneously, nevertheless practical experience and common sense over the past 40,000 years or longer dictate that in fact it is humanly possible,…however, CUM does not here refer to sexual orgasm, but to the Latin word meaning COMBINED TOGETHER WITH.
