The last day of Bootcamp is a rest day. Whatever you do DON'T think about chess. You don't have tostay in bed all day or anything drastic and potentially hazardous like that but stay away from overexerting your brain. Reading is a common restful pastime and I recommend that but not anything that uses too much of your brain. Let the concepts and tactical themes you've gone through soak in a bit today.
Don't be surprised to find your mind wandering toward chess ... it happens to all of us. Don't force the thoughts out but let them run a short course. REST! REST! REST!
