Why choose the picture? In Egyptian the word for rejuvenate literally was "to make green" and is transliterated in English letters as s -w -dj (no vowels, like Hebrew) and could have been pronounced sowage, sewege, or sewage. The symbol is a reed bundle - and it was connected to the post inundation time when everything was green - it also ties into the seasons and the concept of planting.
With exercise, we make our brains 'green' and revitalized amidst an oasis in the desert.
