The older I become, the more I hear claims such as this one, and although I do sense a shift in my perception of a year, or any other period of time for that matter, my logic tells me a year was composed by the same "amount" of time in the past as it is in the present.
Looking back at my childhood, I remember how eternal a day seemed to me, let alone a year. As a five-year old child, a year was a fifth of my life (20%). Today, that ratio is about one twenty-eighth (3.57%). This ratio will continuously change as I reach "old age". Perhaps, if I am fortunate enough to reach 80 years of age and said ratio becomes 1 to 80 (1.25%), I'll become more patient, moderate or "slow". Maybe as an 80 year-old, an hour will seem like a minute...and this will grant me the opportunity to savor my life differently!
I took the liberty of graphing a 1 Year to Age Percentage Ratio Vs. Age which suggests that our perception of time continuously changes exponentially and begins to level out when we reach our thirties, a time during which, in my opinion, many begin to live a stable and orderly life or experience a midlife crisis...
Perhaps if we were to analyze our perception of time and its psychosomatic effect on our lives, we would be able to shift our perspectives in order to make peace with our own impermanence...
