Mr. Li has been retired for three years. When he was young, he often squandered his body. He regretted it when he was old and "could not do anything more". Therefore, he paid special attention to health preservation and took an hour's sleep every day at noon.

But that day he saw an article online saying that the elderly should not take naps, as sleeping too much can easily lead to heart failure. This confused him. Isn't it said that taking a nap is good? How can it be easy to get sick while sleeping?
