There's a saying that goes,  "There is no such thing as a free lunch". Is there such a thing as a free lunch?
I see. So, what about other things? Is there anything that can truly be obtained for free?
It's difficult to say. Some things, like air and sunlight, are available to everyone without cost. However, most things have some sort of cost associated with them, whether it's monetary, effort, or some other form of payment.
