As prime physical specimens, professional athletes may seem invincible, but like anyone else they can suffer from serious conditions that make them vulnerable to the coronavirus.

Hanshin Tigers pitcher Minoru Iwata, who developed type 1 diabetes in high school, knows he belongs to a high-risk group and could suffer greatly if he was to contract COVID-19.

He is faced with a "no-win" situation, having to balance a loss of exercise time as he bids to spend less time outdoors with his responsibility to maintain some level of fitness for when he return to the mound.
