Basic healthcare
Learning about the roles of the internal organs is one thing, but basics such as personal hygiene and what to do with a sprained ankle is another. Pupils who know how to take basic care of themselves and the benefits of these actions will be better protected when they have to fend for themselves.
Some emergency techniques are touched already but they are easily forgotten. For example, how to stop a person choking by using the Heimlich manoeuvre and how to stop bleeding would benefit from being a compulsory, and more frequent, lesson.
