Drinking water can be a meaningful source of microplastics and associated chemicals, including BPA and PFAS, and reverse osmosis is one of the most effective ways to reduce them. I recently installed a reverse osmosis filter on my kitchen faucet. I wanted filtered water not only for drinking and cooking, but also for washing produce. Soil and water contamination can expose fruits and vegetables to persistent chemicals, so this gives me another practical way to reduce daily exposure. The most important thing is to look for an NSF certification that covers the contaminants you care about and review the system’s performance data. That should tell you what the filter has actually been tested to reduce, and by how much. It can also help address concerns about plastic particles being introduced by the filtration system itself. No filter eliminates every exposure. But because we use water every day, reverse osmosis can be a useful way to reduce the total burden from microplastics and persistent chemicals.

Beetroot juice may offer a small boost in aerobic capacity (VO₂ max), particularly for recreational exercisers. A benefit in highly trained athletes isn't clearly demonstrated. Oral bacteria convert beetroot’s nitrate into nitrite, which your body can then convert into nitric oxide. This molecule relaxes blood vessels and may help deliver more oxygen to working muscles. This biology interests me beyond fitness. Years ago, I gave my mother beet extract powder after she was diagnosed with high blood pressure. Two weeks later, her blood pressure measured normal. My mother-in-law had a similar experience! Using beetroot juice for exercise was something I started considering after interviewing @DrAndyGalpin on the podcast! I can attest to its effects after using it multiple times before a hard workout.

Did you know hosted mining has been a thing since 2013? But it's only recently that it's popularity has exploded. Anyone, anywhere, can mine Bitcoin. @LazyMiners1 and @oneminers are two players in this growing industry and if you need liquidity you need look at @ArchLending

This week Del is highlighting @Anchorage, @TicTacc2017, and @simpleminingio as business leaders and exactly the sort of leadership we look forward to seeing in Texas this March.
