Serious question: What actually constitutes a “hybrid” or well-rounded athlete? If someone runs a legitimately fast mile recreationally, will say sub-4:20 and maintains a higher degree of muscle mass But doesn’t prioritize strength training on the big 3 lifts Are they still considered hybrid? At what point does the combo of speed + muscle outweigh elite strength numbers? Would we be more impressed by that 4:20 mile at a larger body size or by someone who can break 5 minutes but deadlifts 600lbs and prioritizes strength still? Curious where people draw the line.

Teabags release billions of microplastics into our tea beverages. A recent study found that commercially available teabags made from nylon, polypropylene, and cellulose release billions of micro- and nano-plastics into a single cup of tea. • Polypropylene teabags released 1.20 billion particles/mL • Cellulose teabags released ~135 million particles/mL • Nylon teabags released 8 million particles/mL In lab experiments, researchers exposed human intestinal cells to microplastic particles and found that different types of plastic interacted with different cell types. Polypropylene particles were absorbed by mucus-producing cells, while cellulose particles were absorbed by two types of mucus-producing cells. Nylon particles, however, were taken up by cells that help maintain the gut's protective barrier but don’t produce mucus. These findings suggest that different types of plastics interact uniquely with gut cells, potentially affecting gut health in distinct ways. While the long-term effects of micro- and nanoplastic exposure remain unclear, it’s evident that these particles are entering our bodies through multiple sources. You might consider switching to loose-leaf tea to reduce exposure if you're a tea drinker. Study: PMID: 39542373
