Roger put 2 and half sea salt(not salt but only sea salt) into water and drink water a lot!!!! its very important for your overall health. you won't urinate much even though you drunk a lot because sea salt holds water inside your body. it will hydrate your body(the most important thing to a body after breathing) which gives you a lot strength to play tennis and better reaction time. you get a lot of sun so i wont talk about getting sun bath.
