If you can keep your head when all about youAre losing theirs and blaming it on you,If you can trust yourself when all men doubt you,But make allowance for their doubting too ...If you can dream—and not make dreams your master;If you can think—and not make thoughts your aim;If you can meet with Triumph and DisasterAnd treat those two impostors just the same ...... If neither foes nor loving friends can hurt you,If all men count with you, but none too much;If you can fill the unforgiving minuteWith sixty seconds’ worth of distance run,Yours is the Earth and everything that’s in it,And—which is more—you’ll be a Man, my son
Manliness includes enjoying toys, whether they are garden tools or drills or mountain bikes or skis or Lego models. There is continuity with Boyliness.
While Manliness has not changed much, there have been changes in who can be Manly. The role was once restricted to penis people. It's now open to all. Once you understand that you can see the continuity of the cultural model.
