看了英文原文，發現我的理解不對，英文很清楚

According to the study, the average 55-year-old’s risk of dementia during their lifetime is 42%, but the risk was not the same at every age. The brunt of it occurred after a person’s 85th birthday. Between ages 55 and 75, the average person’s risk of developing dementia was 4%, according to the study. By the time someone turned 85, their risk was about 20%. Risk didn’t reach 42% until a person’s 95th birthday.

• 在55-75歲之間，一個人患失智症的風險總共隻有4%，不是每年增加4% -dudaan- ♂ (79 bytes) () 01/13/2025 postreply 13:03:16

• 到了95歲，風險增加到42%。若真能活到95歲仍有58%幾率不癡呆呐，知足吧：） -pickshell- ♀ (0 bytes) () 01/13/2025 postreply 13:27:34

• 這裏有一個重要假定是到2060年人的預期壽命會比現在長很多 -dudaan- ♂ (0 bytes) () 01/13/2025 postreply 13:06:06
