I swim alone every morning around 6:30am by Miami Beach, FL and no matter what, I am having a hard time concentrating as I am always afraid of sharks, I keep on looking around and backwards, and find it difficult to keep on the breathing and the pace... Are my fears really exaggerated? Should I really be concerned? Any tips? I know at damn I am at a higher risk, but this is the only time I can due to work...
