How is Chuck's health?

For someone who was more than 80 years old, Chuck did very well. 2011-2012 Chuck had a lingering cold which affected his voice (Which you may notice in his recent John commentary), 2015 to the beginning of 2016 was hard on Chuck as not only did his beloved wife Nancy Missler pass away, but so did his son Mark Missler shortly afterwards, followed by a time spent in the hospital due to pneumonia. In 2017 Chuck retired and then passed away in his sleep, in May of 2018, at the age of 83.
