Here's why:
* Smell and taste are different senses: While smell can give you a hint, it doesn't tell you the full story. Many things smell pleasant but are toxic, poisonous, or harmful to consume.
* Chemicals and toxins: Even harmless-smelling substances might contain chemicals that can be dangerous to ingest.
* Unpredictable reactions: Your body might react unpredictably to an unknown substance, even if it smells fine. You could experience allergic reactions, digestive issues, or even long-term health problems.
Never taste anything unless you are absolutely certain it is safe to consume.
If you're curious about a substance, research it thoroughly, or consult with a knowledgeable person.
