According to scientists, genetics determines between 60% and 80% of an individual's height potential, leaving the rest to environmental factors.

At a temperature of -196°C (-320°F or 77K), nitrogen gas transforms into a cryogenic liquid. The misconception that this represents 'Strong Zero' stems from a Japanese beverage brand, not scientific fact. This article clarifies the vast difference between a specific scientific temperature, a product name, and the concept of absolute zero.

Antioxidants are a class of compounds widely lauded for their health benefits, but confusion still exists around their exact functions. While they are known to neutralize free radicals and protect cells from damage, promoting the development of free radicals is definitively not a function of antioxidants; in fact, it is the exact opposite.
