> Next interesting point. Is giving a speech about how to treat a broken bone considered ‘practicing medicine’?

Regardless of whether it is, you can really tell the hypocrisy. Medicine is a vastly more protected profession than engineer. The article states about 80% of engineers nationwide work legally without a license. That would be unthinkable for any form of medical work.

And yet, there are vastly more people giving out medical advice without a license, and even performing all kinds of quack procedures like faith healing as replacement for medical science.

Some retired engineer talking about his profession while technically not having a license is an absolutely minuscule problem, if it even is one, compared to the reprehensible alternative medicine industry.
