YouTube… but what on earth is this body part called the 'ascending thoracic aorta' (also known as our 'second heart') and what is windkessel effect? Dr Rogers explains both of these nicely in the first 1-2 minutes of the video below on hypertension. Dr Rogers explains that these elastic fibers stop growing & replenishing after the age of 28. With unhealthy lifestyle (staying up late, smoking, alcohol, meat, oils, processed foods, …), we start losing this elastic fiber. In order to retain the integrity of these elastic fibers, we really need to get our act together between 35 and 55 (middle age). If we don't, we tend to lose all that elastic fiber.

A highly technical video that digs into the biochemistry of hypertension.
[Great Video!] Is diabetes & hypertension related to dementia? An insightful presentation by Dr Peter Rogers.
Key idea: capillary wall thickening ("capillary basement membrane" in particular; such thickening is a common feature of diabetes and hypertension due to scarring and inflammation of capillaries) → reduced oxygen supply to cellular structures (neurons, for example) → neuron death → cognitive impairment (dementia).
[The situation is exacerbated by factors like rouleaux formation of RBCs ('blood sludge effect' due to high fat meals), vasoconstriction due to excess sodium (and low potassium, low magnesium), and ramping up of neuronal metabolic demand due to excitotoxins (found in processed foods with MSG, MfG and so on). All of these concepts are explained in detail in other videos by Dr Peter Rogers.]
What to do? Take diabetes and hypertension very seriously (before we become cognitively so impaired that it's too late to take any action): adopt Low Fat, Low Sodium WFPB guidelines diligently. Avoid processed foods.
