Thank you for sharing this information. It certainly helps us to understand what is happening behind the scenes in the body. God bless you!

Throughout life there is a "backup" secondary vascular system of arteries that come about and literally grow to feed the heart. It bathes the heart in blood that carries oxygen to the heart. The heart is a very, very, large muscle. It requires a lot of oxygen and other nourishing elements that are in the blood to keep this large tough muscle pumping throughout a lifetime. It never stops pumping! This muscle continually squeezes (contracts) and releases (rests). Only with time (years) does this "backup" secondary vascular system grow. that system is called THE COLLATERAL SYSTEM. Usually by middle age and older is this secondary vascular system able to function well and almost or fully developed. This is why many older people who have heart attacks from a problem in their arteries can survive. You see, if the heart muscle starves from a blocked artery or a similar reason, this backup network of arteries that are specific to the heart continues to carry blood to the heart muscle. The "collateral circulation takes up the slack." Only the heart has one! No other organ muscle does, not even the brain. So, the heart has to work hard in an older person But remember, they have a secondary backup of blood that gives the heart oxygen through blood. That's because the collateral circulation has fully developed. So while they may suffer a heart attack, it doesn't starve the heart totally. A heart attack is when the heart muscle dies in part from lack of oxygen. That pump can't pump like it use to because its been injured. But what happens when a younger person's heart is starved of getting enough oxygen from the blood? They too have a heart attack! The oxygen doesn't get to the heart fast enough so the muscle doesn't get enough oxygen fast enough to maintain the muscle. The muscle gets a cramp and becomes injured to the extent that it doesn't pump blood. That muscle ---that heart---doesn't have enough oxygen, it quickly starves until it stops pumping altogether. When the heart beats faster, it requires more oxygen. So when we run and become active, our heart needs more oxygen---more blood flowing. Interestingly, with extensive training (multiple years of training), an athlete's heart will actually beat a bit slower than a normal person during heavy exercise. But those particular athletes have trained for many years and years. A trained athletes heart actually beats slower during heavy exercise than an younger or untrained heart. It has been trained to do that over many years. Yet many athletes, especially those in college or sports are younger people and they haven't become fully trained athletes over many years. Their hearts have not been trained over multiple years to beat slower during heavy exercize. As well, remember the younger person hasn't fully developed a collateral network of arteries that surround their hearts as a back up. So if a younger person has a heart attack, they have no backup system that can function to protect their hearts and deliver more oxygen. I believe this is why we are seeing athletes and younger people and kids playing sports die and fall out instantly to death. There is an additional reason that comes to mind. The Spike protein that is carried freely in the blood has sharp edges like glass. These sharp edges scrape and scratch the inside of arteries and veins that injure the linings of the vessels and tiny capillary trails. And I have seen in electron microscopic pictures where Spike proteins even clump and clog and block the capillary trails that also carry blood to cells. When we are injured inside of our bodies inflammation happens. Inflammation signals our immune systems to rush antibodies to the site of injury to kill foreign bacteria, or virus's. Other cells also come to our rescue. Sometimes we can see a semi-clear fluid build up in a wound. That fluid is full of white blood cells that take care of the wound and carry away broken cells that don't work any longer. Medical establishment has verified the effects of the spike protein in multiple organs. The heart is also an organ. I believe the heart is damaged, as well as our blood vessels because of the spike protein and because of the spike protein causing an abundant reaction of our own immune responses to damage of that spike protein. An alteration in the saturation of oxygen in the blood is also effected in multiple ways. But we must remember that these younger athletes have no additional back up system like a middle age or older person to feed or maintain the heart. It could also be that because of the spike protein, that the vascular (arteries and veins) have been poked and damaged causing inflammation ---thus the "pipeline" inside the vessel is more narrow, thus carries less volume of blood. (Like a narrow pipe versus a large round pipe). Doctors know this, but they are not saying it. Giving the koolaid to any younger person is insanity and from the pit of hell in my opinion.
