Primary or focal hyperhidrosis may be further divided by the area affected, for instance palmoplantar hyperhidrosis (symptomatic sweating of only the hands or feet) or gustatory hyperhidrosis (sweating of the face or chest a few moments after eating certain foods).
The proverb The proof of the pudding is in the eating dates back to at least the 14th century. 1  The phrase is widely attributed to the Spanish author Cervantes in his novel The Ingenious Gentleman Don Quixote. The phrase is often incorrectly stated as the proof is in the pudding..
The original expression means that you can't know whether something will work or will be any good until you actually try it out yourself. This is especially true for something that sounds good in theory but has yet to be proven. (This pudding was prepared by a master chef, so is it any good? I don't know, let's taste it and find out.)
