retraining of students might be another financial and labor drain on schools, although this problem could be ameliorated by introducing the subject in the junior year of high school, thus saddling colleges with the task of recertification.
     6. Training of trainers . “A little knowledge is a dangerous thing,” emphasizes Ira Schwartz, project director of the New York State Regents Advisory Committee on Community Involvement. Schwartz and others we talked to thought that finding a ready supply of teachers qualified to teach CPR, or training nonqualified teachers to do so, was a major hurdle.
     7. Competition . CPR isn’t the only health item clamoring to be included in public school curriculums. Although she joined in the chorus of educators who thought that universal CPR training would be a noble idea, Arlene Sheffield, director of the school health demonstration program for the New York State Education Department, told us that many educators believe that teaching students about bulimia, anorexia nervosa, and child abuse has a higher priority. Sheffield’s program, for example, focuses on eliminating drug abuse among students, a subject of more pressing importance to students, educators, and parents than CPR. As Sheffield puts it,

     The pool of money and time available for schooling in any given subject is finite and CPR and first aid have a lot of healthy competition.
     
    CPR training is not totally abandoned in our public schools. Many schools offer kids training on an elective basis; community groups and hospitals offer low-cost courses. And a few public school systems, such as Seattle’s, find the time, money, and training resources to offer all students CPR courses.
    Charles Myers was not alone in wondering if some of that time he (and, let us admit, we) wasted in school might have been better spend learning a skill that could save others’ lives. When we asked Emmanuel M. Goldman, former publisher of Curriculum Review , this Imponderable, he echoed our sentiments exactly:
     
         As to why CPR isn’t taught, at least in high school: It beats me. Probably because it is such a logical, desirable, and useful skill.

    Why Do Peanuts in the Shell Usually Grow in Pairs?
     
    Botany 101. A peanut is not a nut but a legume, closer biologically to a pea or a bean than a walnut or pecan. Each ovary of the plant usually releases one seed per pod, and all normal shells contain more than one ovary.
    But not all peanut shells contain two seeds. We are most familiar with Virginia peanuts, which usually contain two but occasionally sprout mutants that feature one, three, or four. Valencia and Spanish peanuts boast three to five seeds per shell.
    Traditionally, breeders have chosen to develop two-seeded pods for a practical reason: Two-seeders are much easier to shell. According to Charles Simpson, of Texas A & M’s Texas Agricultural Experiment Station, there is little taste difference among the varieties of peanuts, but the three-seed peanuts are quite difficult to shell, requiring tremendous pressure to open without damaging the legume. We do know that patrons of baseball games wouldn’t abide the lack of immediate gratification. They’d much rather plop two peanuts than three into their mouths, at least if it means less toil and more beer consumption.

    Why Are Children Taught How to Print Before They Learn Cursive Handwriting?
     
    While most of us were taught how to print in kindergarten and learned how to write in late second or third grade, this wasn’t always the case. Until the early 1920s, children were taught only cursive handwriting in school. Margaret Wise imported the idea of starting kids with manuscript writing (or printing) from England in 1921, and her method has become nearly universal in North America ever since.
    Wise used two arguments to promote
