I worked in the ED for a decade and this is very true. Avocado injuries might be the most common non allergic good injury. I do mine like this guy says. Usually 3 or 4 a day. I only use butter knives to cut them and the wacking the seed still works. I then take the knife and make either slices or grids in the fruit while it is in the peel and use a spoon to scoop out the pre cut flesh
