If that issue of slowing down is based on the perception of others, it is false. There is an old saying. 'If you only knew how little time others spend thinking of you, you would not worry so much about what they think of you.'

A simple explanation is sufficient. 'I suffered a traumatic brain injury and needed to slow down and take some time off. I recovered and am doing great now.' Those that choose to not accept that explanation have their own issues.

That is a much easier explanation than the roller coaster of PCS interrupting ones life for years.

In my view, it appears most young people are not as concerned about what others think but rather do not want to miss out on partying and stressful entertainment. There are plenty of social circles that do not involve such brain stressful activities.
