He was a little bit aquatic.
When he was young and reckless, he had a very poor swimming ability and could only pull off a desperate 'doggy paddle'. Yet, he was daring enough to frequently play with the village kids in the river and reservoir.
As he grew older, he began to learn caution from the many stories of drowning incidents he heard or witnessed.
"In terms of stroke style, swimming is divided into backstroke, breaststroke, butterfly stroke, and freestyle."
"However, for the purpose of learning, it's unlikely that such fine distinctions will be recognized. It's probable that it will be categorized like running, divided into short distance swimming and middle-to-long distance swimming."
"If I plan to learn, I could temporarily classify anything under 800 meters as short-distance swimming and anything above as mid-to-long distance swimming. Then, like sprinting and middle-to-long distance running, I can get attribute points from both the swimming activities, haha."
