If you are getting more forgetful with the years, all is not lost. It’s more about remembering the central, crucial, meaningful things than about being able to rattle off all of your codes and passwords, your second cousins’ birthdays, or the conversion tables for metric-to-imperial measurements. It doesn’t matter terribly if you can recall whether you closed the back gate when you came in, since you’ll eventually go out again. Recollections of your intent to mark a play you want to attend on your calendar because it’ll be in town in six weeks or of what you meant to buy when you got to the grocers’ might be important, but only for a short while, and only in the smaller scheme of things.
It’s much more important to remember the peculiarly exciting, if murky, odors of a busy train station where you waited to take your first solo journey of more than ten city blocks, at the tender age of thirteen or so. More useful to recall the sound your heart made in your ears when that feral and atavistic fear and longing of new love brought its strangely sweet and terrifying joy into your central nervous system for the very first time. It’s far and away more significant to remember that you ever had a single human, known to you or an utter stranger, who looked you straight in the eye and said a kind word, or who listened to you speak because it genuinely mattered what you said, regardless of how small the topic.
It’s most important of all to remember that your presence on this planet shifts the very molecules of time, space, and reality for every other living entity, and did so from the instant of your conception and will do so forever and ever after you, simply because you came into existence. You are matter, and you do matter. What positive effects you can have by merely being present here might seem infinitesimally minute to you. But for one other being, someone you didn’t even realize could be so affected, you might be that person who looked her straight in the eye and said a kind word, the object of electrifying first love, or the indirect yet needful reason a youth boards a train, solo, for the first and most memorable journey of his life.
