Question

求翻译——roll off的具体意思以及water off(from也可以？) a duck's back

"If people were supportive of the movement, a message like that might roll off it like water from a duck's back, " he says.
我理解的意思是：人们是会支持这项运动，像这样的言语可能如同roll off(耳旁风？)一样毫无作用。
求助一：能否给以上这句话以更精准合适的翻译？

求助二：我在别处学到"water off a duck's back“的意思是“毫无作用”，句中将"off"改成了"from"是否也是可以的？

求助三（主要的）：roll off在这句话里表示的意思是什么？我还有一句话：："The doctors tell us it`s dangerous to smoke, but such good advice rolls off some people like water off a duck's back."
这是说：“医生都告诉我们抽烟对身体是有害的。可是，这种劝告对于有些人来说就像耳边风一样，毫无作用。”
上面这句话把roll off翻译成了耳边风，是不是可以这样翻译，还有更好的翻译解释吗？
