For a person who considers herself happily immature relative to her age, I am sometimes caught off guard when I realize how little of my youthful pleasures I’ve continued to pursue with appropriate enthusiasm into the present. Why on earth would I forego standing on a big plank swing, grasping the chains that hold it and me up, and pumping my legs until I feel like I could fly right on over the top steel bar of the swing set with the greatest of ease? Why not kick off my shoes and socks, abandon them in the dirt, and plunge into the cold river’s slippery, rock-strewn flow without regard for getting the legs of my pants all soaking wet? Is there any law that says a 52-year-old is no longer allowed to slurp her fruit punch noisily through a straw just because it’s so wonderfully refreshing and sugary?

Why, indeed, is the common phrase seemingly always about youthful enthusiasm, yet we tacitly agree to let only actual youths embrace it?

Remind me how being childlike and impulsively happy is so dangerous.

Despite being of an age where my childhood version of the high swing was of rock-hard rubber on a steel pipe frame and underlaid with gravel-strewn dirt, I am—well—still alive at this age. I never broke a single bone or chipped a tooth, and my only stitches derived from an indoor activity, a school game of floor hockey. Though I wandered recklessly through many a stream and ocean’s shallows, without regard for my pants or my tender soles, and even drank from the occasional icy mountain brook, the worst that ever came of it was a cut from beach glass, soon enough cleansed with stinging but healing salt water. No clothes were ruined, and I got bit by nothing bigger than a sand- or horse-fly or two. I failed to contract Giardia or E. coli from those wild rivulets I sipped. Even the vast quantities of evil cyclamates in my childhood fruit drink binges failed to kill me off.

So how is it that I lost my ability to plunge ahead without caution to where I seemed, nearly always, to find joyful things? Remind me how always being responsible and mature and playing it safe is better for me.

But write it in a note and slip it under my door. I feel the need to go out and look for a little happy trouble.
