Now, in truth, someone doesn't have to have a better suggestion in order to point out that a recommended strategy will exacerbate the situation. If an allergic man has been stung by a bee, I don't know what to do except rush him to the hospital and maybe scour the cupboards looking for Benadryl. But I'm pretty sure drawing blood from his leg, in order to inject it into his arm and thus "stimulate his immune system," is a bad idea on numerous accounts — not least of which, is that I'm pretty sure an allergic reaction means your immune system needs to calm down. But the point is, if a bunch of guys hold the man down — he has to be forced to endure the procedure for his own good, don't you know — I feel perfectly qualified in yelling, "Stop!"
