The Deepest Ocean Trenches Are Near Freezing Temperatures

Despite immense pressure, the water in the deepest parts of the ocean, like the Mariana Trench, remains incredibly cold, typically between 1-4°C (34-39°F). This is because sunlight cannot penetrate these depths, and cold, dense surface waters eventually sink to fill these abyssal plains, creating a perpetually frigid environment.

Gastric acid (hydrochloric acid) has a pH of around 1.5 to 3.5 — corrosive enough to dissolve metallic zinc. The stomach doesn't digest itself because it is continuously coated by a thick mucus layer. Stomach lining cells are replaced entirely every 3–5 days to prevent acid damage.

The Human Nose Can Distinguish Over 1 Trillion Different Scents

A 2014 study published in Science (Bushdid et al., Rockefeller University) revealed that humans can discriminate at least 1 trillion distinct odors — far exceeding the long-held estimate of 10,000. The olfactory system uses around 400 different receptor types that combine to create millions of scent signatures.
