Dude I would definately get that shortness of breath checked out, it's like a dodgy booty call. It's like watching dads army go hunting, no offence intended.
I thought about taking a camcorder and filming my shots but most the time it's hard enough worrying about a good shot let alone faffing around with a camcorder as well, so well done for trying it.
I think the only time I would film it is if my shooting partner was shooting and I just sat their filming for him.
