I'm fat and may have hyberhidrosis (bitter exaggeration). It's rather amazing how easily and how much I sweat. "It's room temperature and he's standing still doing nothing!!?! Quick engage sweat glands or he's gonna overheat!!" Even before I was fat, I sweated/swat (? lol) a lot.
Also, I'm near-sighted and have minor thoracic scoliosis. Guess the examiners failed when they checked me for it in middle school. The weird part is: my left rib cage and left side of my back along the spine have always been higher than the other side. Why didn't they think that was a sign? I only found out about the scoliosis around 5 years later. Fortunately, it doesn't appear to affect me negatively.
In short, I'm fortunate not to have any health problems too outside of my control. Except the sweating, hopefully if I ever get in shape, that problem will be significantly reduced.
