Lol I used to work with C4. I have used the tech I am talking about. It can sense the scent of C4 on a person's hands that have been washed numerous times. It can detect it through packaging. C4 literally comes in plastic wrapping and is detected through it.

This doesn't seem like a good excuse considering that there are devices that can sniff out C4, as it has a very distinct scent. There is literally no reason to believe that peanut butter is C4. If they actually cared about safety they would just invest in tools that identified actual threats instead of just making life harder for people traveling.

Elderly people are a danger in vehicles. Shit, half the people I see driving are.

Coping is likely huge. But in my case (ADHD diagnosed as an adult) I tend to avoid situations that would exacerbate issues that derive from ADHD. As a child you don't have that luxury.
