Oddly enough for a lover of aquatic life, Lin has never learned how to swim, and it almost proved fatal once when he was trying to pick a stem of bladderwort at Shuanglien Pi. He lost his balance and fell into the lake, but luckily managed to grab onto a clump of grass and pull himself to safety.
他曾為了採一小枝「狸藻」，一頭栽進雙連埤，不會游泳的他，攀住一旁的芒草才爬上岸。
