I've always prided myself on excellent eyesight. But I have had to concede in recent years that my eyes are simply nowhere near as good as they used to be. I have been trying to convince myself that it's a natural consequence of aging :) After all, many people develop presbyopia as they get older (where you gradually lose the ability to focus on close-up objects). But I've been forced to admit that aging's role is only a small part of the story for me. Because when it comes to the end of a long day in front of my computer, my eyes just don't work as well. Things get a bit blurry. My eyes are tired and overworked. Dhruvin Patel can help with that. His company is Ocushield, and as you'll hear he's got a deep knowledge of the science of our eyesight and what's going on with screens. THIS SHOW IS BROUGHT TO YOU BY: BiOptimizers — Four out of five Americans are magnesium deficient, and almost everyone is at suboptimal levels. That's a big problem because magnesium is involved in more than 600 biochemical reactions in your body. Now here's what most people DON'T know: taking just any magnesium supplement won't solve your problem because most supplements use the cheapest kinds that your body can't use or absorb. That's why I exclusively recommend Magnesium Breakthrough. It's the only full-spectrum magnesium supplement with seven unique forms of magnesium that your body can actually use and absorb. When you get all seven critical forms of magnesium, pretty much every function in your body gets upgraded. From your brain to your sleep, pain, inflammation and less stress. Here comes the best part: the makers of Magnesium Breakthrough - BiOptimizers - are having an incredible Black Friday special offer from November 21st to 29th. You can get - not only Magnesium Breakthrough - but all of BiOptimizers best in class products with 25% off. (In the UK, the discount is 10% not 25%)
