Anecdotal evidence. I've known security guards that were athletes before the job and they all said the same: "I could do various sports (or hike in the mountains) for 14-15h before needing to sleep but stand around guarding a shop for just 1h and I am more tired compared to what I was doing those 14-15h in the past". Be grateful for your health, seriously. A lot of us aren't elves with unlimited energy. Also I don't want to be mean but your advice is super shallow and practically ignored everything I said in my previous comment.
