If you try out these good ideas and still cry while cutting onions, don't worry.Scientists think if you cut more onions, your body will become more resilient to the onion's chemicals.So the tears will not last long.If you think about how healthy onions are, you might even call those tears “happy tears”. 1.Onions can help you fight off sickness because they have .
