Taoiron, I'm not trying to be an ass, but what is it that you do that your life may depend on your workouts.
I have done a lot of work where I definitely had to rely on my size and strength.
I am approached a lot with questions while in the gym. I have no problem talking with people and I always get in a good workout.
I have been to the gyms in Venice many times and met and worked out along side some of the biggest names in bodybuilding. And those guys would actually carry most of the conversation.
The only time I won't talk is in the middle of a set.
It all just boils down to ones personality.
