What does the familiar saying "Kill two birds with one stone" mean?
Getting two things done in one effort
Do two things at the same time.
Taking care of two problems at once
You do two things, while only using one attempt. Like you throw a stone, and kill the bird you were aiming for, and killed another one. You got a two for one deal.
doing two things at once ? i think ..
If it takes two stones to kill two birds would it not be wiser and cheaper to use one stone to kill two birds?
Birds can be pests. The saying means to take care of those two problems all at once.
Say you lost weight, you are healthy and you look good,
