The surprising earliness of decline

: in practically every high-skill profession, decline sets in sometime between one’s late thirties and early fifties. Sorry, I know that stings. And it gets worse: the more accomplished one is at the peak of one’s career, the more pronounced decline seems once it has set in

Vitamin B12 deficiency, common in individuals following plant-based diets without adequate supplementation or fortified foods, can lead to elevated levels of homocysteine in the blood, which is recognized as a risk factor for stroke.
While there is ongoing debate regarding the association between homocysteine levels and stroke risk, observational studies suggest a link between higher homocysteine levels and increased risk of both ischemic and hemorrhagic strokes, as well as cardiovascular mortality.
Studies, such as the EPIC-Oxford study, have found that a significant proportion of vegetarians and vegans have vitamin B12 deficiency, leading to elevated homocysteine levels and potentially increasing their risk of stroke.
Interventional studies have demonstrated that vitamin B12 supplementation can improve arterial function in vegetarians with subnormal B12 status. This suggests that addressing B12 deficiency may mitigate the increased stroke risk associated with plant-based diets lacking sufficient B12 intake.
Despite the evidence highlighting the importance of B12 supplementation, many vegetarians resist taking B12 supplements due to misconceptions about B12 deficiency being rare or assuming that dairy and eggs can provide an adequate B12 intake, emphasizing the need for education and awareness on the topic.

The picture this theory paints of the subatomic world is perplexing: particles can seemingly exist in two places at once, time stands still and there is no such thing as empty space.
