Prevention is better than cure

That depends on what we define as better.

I know prevention is less complicated.

I know prevention is less costly.

I know prevention is less time consuming.

I know prevention is less physically painful.

When I don't take care of my health (i.e. drink water, take my meals regularly, exercise...), I end up with health complications. When that happens, I have to find time to make appointments with the doctor, undergo some medical procedures, pay a hefty sum...

I wonder whether I can save myself trouble by making some effort in the first place.
