Over the years we've seen some extremely good players bow out of the scene due to various injuries and long term issues. If we look at most physical sports, the last 30 odd years have had huge advancements in athlete conditioning leading to greater performance and in some cases longer careers.
I'd like to know more about whether the SC2 scene and Esports in general have people looking at the long term fitness of top level players. If you've got any info to share, please do so!
I believe Starcraft to be the most physically demanding Esport so it's clear we'll require longevity from our players to sustain and build a consistent scene over time.
