The summer heat is hard to beat most days. It totally sucks to get sweaty and over heated. I find that the best way to stay cool on some of the hottest days is to spend some time in a nice cool pool.
The smell of the chlorine is one that I have always associated with summer. It totally reminds me of the days when I was younger, spending my summer days, in the family pool, with friends, laughing and splashing, or just relaxing in the cool clear water.
And of course there is just fully relaxing, while getting some sun. Just let the mind empty as you get a good tan. All your troubles can float away if only for a few hours.
