What is the impact of chronic pain on the ability of a young man to tolerate chronic pain?

In Davidge v. Fairholm, 2014 BCSC 1948 at para. 166, various factors were discussed as supporting a conclusion of a real and substantial possibility of a future loss on the part of a young plaintiff which included: 1. The plaintiff had a relatively high level of chronic pain; 2. The plaintiff’s job required a great deal of concentration; 3. The plaintiff’s job put physical stresses on his body; 4. The plaintiff had physical limitations preventing him from performing even more physically demanding tasks than those he performs in his present job; 5. As a matter of ordinary human experience and common sense, a person’s ability to tolerate chronic pain diminishes with age.
