Thanks for your answer.
The 10kg of my gear are really not a problem (my daily bag weights about the same), and extreme temperatures are rarely met in this season. For the adrenaline shot, apart from increasing heart beats (not that much from data I got wearing a heart monitor belt) and heart output, how could it be worse than pumping to the max after some uphill running workout ? (which was not recommended for *only* 1 month)
The doctor first announced 1 big month without skydiving, which transformed to 3 months once I was all cabled-up for the operation... It really looks like some extra and unnecessary last minute precaution from someone who does not know the sport, and refuses to admit his ignorance, as many doctors unfortunately do. (I asked what were the specific numbers I should monitor, he brushed off the question)
