Clandestine,

Although I do not go into a panic state such as yourself I do find myself much more alert and my head on a swivel while walking outside and especially when crossing streets.

I don't really understand how it developed as I was hurt on the water also but I am definetly more attentive to cars...I just don't want my head hit.

Develope a thorough and sensible scanning technique with eyes and ears then make yourself trust yourself.

You can do it!

Bud
