Ex 1 (expression of pain): *stubs toes against table leg* "That's Fast!"

Fasting for one day is not physically or mentally unbearable or unendurable, and doesn't cause major health problems for most people, which is why most major religions include fasting as part of their seasonal duties.
The guy/girl was feeling weak after one day of fasting. Fasting for one day is not unbearable, just about anybody, if not anybody can do it. Some people would be glad if fasting was something they did by choice instead of because they have nothing to eat.

What Is Fasting?
Fasting is when you consume no food or drinks, with the exception of water, for a set period of time. It’s important to drink plenty of water, not just because you’re not eating, but because it’s easier to draw blood from your veins when you’re well hydrated.
