Exactly correct.   I was absolutely certain about the penalty (none here), but the bit about where they play from can be really confusing the first time you read it.  In my big paper rule book, i used colored highlighters to make it clear.  Good thing I did, at the Cascades there's little to no cell service, so using the rules app on the phone wasnn't possible.  

Taking a crack it, but looks pretty clear. 11.1  Ball in Motion Accidentally Hits Person or Outside Influence. a. No Penalty to Any Player If a player’s ball in motion accidentally hits any person (including the player) or outside influence: There is no penalty to any player. This is true even if the ball hits the player, the opponent or any other player or any of their caddies or equipment. Reading further down it looks like they have to play the ball as it lies. No replay from the previous spot. 

I had an interesting one yesterday, a local qualifier for the US Senior Open, at the Cascades Course at the Homestead.  Well, first things first, the VSGA arrnged for the officials to play the Cascades on Monday at the players' practice round rate.  Its lots of fun, rather old-style (built in the 1920s).  anyway, a player missed a short putt, and (apparently embarrassed) took a step to be ready to tap the ball back in.  The ball lipped out, and hit the player's foot.  I was nearby, and they waved me over, and asked "What do we do now?"  I was pretty sure of the ruling, but asked them to wait for a few seconds while i double-checked.  I did have it correct, even though its one of the more confusing rules in the book right now.  I'll leave the correct answer out for now, in case anyone wants to guess, or research it, and post their ruling.

I am going to try to try to have more intent with my shot routines. I saw this process in a YouTube video I watched last night.  Decide what you want to happen - Yardage, shot shape, start line Visualize what you want to happen - Straight forward, but one tip he suggested was while focusing the shot take in a slow deep breath (like 4 seconds in duration), hold for 1 second, then exhale slowly (like 4 seconds again). There is some evidence to show that this rhythmic style of breathing can help in calming heart rate and improving focus.  Feel what you want to happen. - Your 1-2 practice swings. Like if you need to hit your PW at 90%, feeling that.  Commit to what you want to happen on the ball.  Post-shot routine, where you either gain confidence from a good shot or learn from a mistake to foster a growth mentality. - If it was a good shot then give yourself some good vibes/feedback. If the shot didn't turn out, then access why to learn from it. I am going to add, don't get negative. 

I mean, if you like GZ, and would drink it more often during a round than water, then keep drinking that. If you walk 18 holes, on a hot summer day, and drink 2 20-oz waters or 4 20-oz GZ. You will benefit more from the 4 20-oz GZ because it's like 99.99% water, lol. Yea, if flavored water makes you drink more water, then that works better.  I would just monitor the salt intake relative to your own health. I am sure some people might have to be careful. GZ is 280 mg salt. So, 4 of those is over 1000 mg. It is over 4 hours. That is like half the daily recommended intake of salt. You are probably losing some of your salt reserves playing golf. Long winded way of saying, it depends on the person.
