Yeah watched Master Kim a lot. And he always has fun sketching and interacting with people as his job. This wasn't his job, just his passion. Definitely genetic factors, etc, can lead to cardiovascular disease...we don't know every thing to comment. He was getting tired, more from traveling around a lot, as I talked to some of his entourage a week before his passing, don't know how much that affected his heart health.
I personally find this anecdote really shitty to be honest. Only a balanced mind and body can sustaine quality over a long time.
Also bad health in old age is super critical for living long and bad. Would never thrive for this like laying in bed having pain every day being dependent
