I never understood panic attacks, stressing and panicking in any situation is never good. I assume it's a 'can't stop it' kinda thing?
I always thought especially when cycling or riding my motorbikes is the experiences stop any worries that I have, a lot of ppl worry about crashing especially on motorbikes but after having more than I care to mention my attitude towards them now are more like "damnit not again" than "oh sh*t Oh SH*T"
