  • 30 fl oz is A LOT of beverage, a normal sized energy drink is more like 8-16 fl oz, and usually has only 100-200 mg caffeine tops. I’ve noticed a lot of 300 mg drinks start to get phased out in favor of drinks that only have 120 mg, which is actually a pretty reasonable amount for an adult.

    For instance, I’m about 190 lbs and I need close to 250 mg to adequately feel its effects for exercise, and there are studies that show this is an appropriate amount (mg/lb) for exercise benefits.

    However, even though 30 fl oz with 390 mg is about in line with the smaller drinks for caffeine/volume, I think ideally they should just not offer such a large size drink.





  • We don’t have sensors to directly sense a single magnetic field, but if you’ve played with magnets a lot, you can definitely “feel” how their forces work and develop kind of an intuitive physical sense.

    Perhaps a good example/analogy of something we can feel and understand somewhat intuitively but actually do not scientifically understand is gravity. You can definitely feel its effects / force, even though you don’t have a specific gravitational field sensor in your body per say.

    We have very good theories and formulas for calculating gravitational effects, but we still fundamentally do not understand what causes it.
