I loved his anecdote of doing jumping jacks while having a panic attack. The lightheartedness of the way he approaches the disorder is kind of nice.
One weird thing that helped me was reading everything I could possibly find on panic attacks over some short period of time. Every paper, book, medication, etc. Unlike some disorders, the truth seems to mostly be positive (non-dangerous, relatively straight-forward ways to beat it), and so the more you know the better you'll be at approaching it.
