At an early age, I exhibited amazingly acute scientific observational abilities.For instance, during the first 20 years of my life, I noticed that both of my parents (now dearly departed) progressively shrank. I first attributed their diminution to mass-loss in the Universe due to the effects of proton decay, but now I'm not so sure.
It's the Einstein Lorentz length contraction due to velocity increase.
