Question

It is healthier to smile
than frown. Explain.​

Answer 1

It breaks down fats that are eaten, converting excess carbohydrates and protein into forms that are stored for later use, while synthesizing other fat, like cholesterol. The liver produces bile to help break down and absorb fats. Waste products and toxins are removed through bile.

Answer 2

Actually, there isn't any proof behind this old saying. Scientists have studied the muscles needed for both facial expressions, and to do a small smile generally uses 10 muscles; a small frown uses 6. On average, a smile uses 12 and a frown 11. However, since humans tend to smile a lot, these muscles are stronger.
