AGAINST #AGISM: A Paradigm Shift!

I've been really enjoying the excellent science videos on YouTube! Relativistic physics, quantum mechanics, archaeology, astrophysics, geology, biochemistry, fantasy archaeology, ufology, cognitive psychology, etc.
For those who've never heard of the existence of "fantastic archaeology," I suggest searching online for "Graham Hancock," an extremely creative English journalist who delights us with advanced and ancient civilizations, predating Atlantis itself. With a fantastic. mighty imagination, Graham raves about far-fetched hypotheses without any basis in the real science of archeology.
Undeniably, youtube has several high-level science channels, which even estimulate us to create our own proposals to several challenges faced by most advanced theories.
Is quantum mechanics wrong or incomplete, as Einstein uttered when had reluctantly to accept it after its undeniable practical results.
For ordinary people it seems much easier to think the genius is right and not the theory, right?
Wrong: you can't accept anyone's opinion on empirical science questions, not even those of the greatest geniuses, without objective, rational proof.

Taking into account the speedy unfoldings in Physics in the last 200 years, we may infere that bold hypotheses are mighty propulsors of scientific revolutions, so why shouldn't laymen and laywomen try our own solutions to appaently unsolvable problems?

Thus, encouraged by science youtubers, based on my own present experiences concerning falling things and comparing them with my memories over passing decades, this bold hypothesis came to mind:

Contrary to what classical physicists teach us, gravity, whether a field, force, or curved spacetime, does not have a fixed and unchangeble value on the Earth's surface. 

Instead, it actually becomes stronger in infinitesimal increments, only noticeable over lvery ong periods.

This could sure explain why, after dinosaurs' extinction, the average size of Earth's animal species decreased so clearly.

Over the ages, the centuries, the decades, the years—all the time long, in short, being heavier became an increasingly limiting factor in the struggle for survival. This would have favored the selection of ever lighter, more agile species.

Darwin would support such a hypothetical reasoning, wouldn't he?

Trying to inquire the strength of this hypothesis it is surely   mandatory the gathering of as many as possible testimonials like mine. To begin with it,  a simple question is addressed here to those who among you readers have been on this planet for longer, specially if for more than five decades:

Do you confirm my observation that gravity is getting stronger? Have you been noticing that objects fall from your hands much more often than they did in your sweet, divine phase, i.e., your youth?

PS1: I know many people will try to see in this hypothesis the power to explain why over the years her or his weight only increases uninterruptedly over time. Excuse me, but that's for another research that must be at least as rigorous as this present one.

PS2: Yes, this strange gravitational phenomenon certainly impairs male sexual performance.

[But not mine, of course!]
