How can you learn from others about health?

Learning from others depends on people's ability to integrate their own and others' experiences. In order to do that successfully, people have to abstract from single experiences (that they themselves or others have had) and recognize those features that different situations have in common.

The life lessons will of course differ from person to person as we are all different, have different illnesses or injuries and life circumstances. For a start I am focusing on the life lessons learned from illness I have experience with.
To keep this post within a reasonable word count, because this could end up being a long post, I am focusing on 11 life lessons (it was 10 originally). But having a ‘top 11’ is in no way meant to turn this into some sort of cliché and devalue the topic. This is a big topic, and a very important one given the lessons learned often have a lifelong impact.
And when I talk about an illness or injury, it could be your own, a loved one’s, a relative, friend or colleague.
