Mmhh...

I didn't say all pain was evil or unpleasant, quite the opposite.

I quote:

"This is why you feel so good after:

Exercising

Cold and heat exposure

Telling the truth

*Not* taking the easiest path

Working hard

These are healthy stuff."

There is bad pain, and good pain. Yet I'd say both are unpleasant.

The "healthy" pain simply tends to feel "pleasurable" because it yields positiv results in the end.

Besides this exception, I am ready to bet that the majority of people would describe all types of pain as unpleasant.

Hence the article.
