Sounds like we need to define "suffering"

For example, if everything was known and easy, wouldn't we be completely bored? Is boredom not also suffering?

I'm pretty much thinking of the definition from the 1913 edition of Websters: "Suf"fer*ing, n. The bearing of pain, inconvenience, or loss; pain endured; distress, loss, or injury incurred; as, sufferings by pain or sorrow; sufferings by want or by wrongs."
