WORNOUT TIME (wt) at the End of One’s Lifetime: When the Lower Standard Deviation Curve (LSDC) of the Lognormal Process Finally Intercepts the Time Axis

The present final Chapter “WORNOUT TIME (wt) at the End of One’s Lifetime: When the Lower Standard Deviation Curve (LSDC) of the Lognormal Process Finally Intercepts the Time Axis” is the continuation of the previous Chapter “MOLECULAR CLOCK as a Stochastic Process: Evo-Entropy (Shannon Entropy of Evolution) of a Geometric Brownian Motion (GBM)”. It deals with our new discovery, made on May 10th, 2020, that all Living Species will, sooner or later, undergo their WORNOUT TIME (wt) at which they DIE and disappear from Earth. In mathematical words, we discovered that, sooner or later, the Lower Standard Deviation Curve (LSDC) of Life will certainly intercept the time axis, thus bringing the probability of DYING very high, approximately just before or just after that interception point (wornout point i.e. wornout time). This result came as a “surprise” to this author, since he was convinced that the LSD curve “kept away” from time axis just as the USD curve and the mean value can do if their derivative was positive for all times, including the range between ts and infinity. But that is not the case for the Lower Standard Deviation curve, as we now prove.
