Hello members! Today, I was in my study room, and my brother came in and startled me by shouting suddenly at mu ear, I was absorbed at my work and I had not expected him so I was startled. I wonder what native speakers say in situation like this. Would you say "You have shortened my life by ten years!" if somebody had just scared you and you were complaining about it? Should the "life" be "life span" instead? Is that idiomatic? Thanks so much!
