“We can't live without humor”

Is this really true? If we interpret this sentence in a literally, absolutely non-metaphoric way, it's easy to talk nonsense: Humor is completely vital for life and without it, we will die. Obviously, to discuss this phrase we need to understand it as a metaphorical one.

On one hand, having a favorite topic for jokes doesn't mean the others would find comfortable with it, and you can easily offend or make someone feel bad; otherwise we would all have the same type of humor. The same occurs if we are jokers; we may see it funny, but it can be painful for the person who “suffered” the joke. So, humor can make your life and other's ones tough.

However, on the other hand humour affects positively to your relations and behaviour, greatly increasing your sense of self-fulfillment and making you engage your life happier. Well, life can be really deceptive, and it's absolutely true that if the bad things aren't faced with positiveness, they can make you suffer a lot.

In conclusion, humor is kinda “useful” if we want to avoid suffering, but on an adequate measure; in other words, having no humor at all doesn't help you much, but having an “uncontrolled” one have similar consequences.
