We can do this! In fact, we ARE doing it. All that online passion – the tweets, retweets, tagging and hash tagging – is having an effect. It’s impressing some, concerning others, but surprising all. It’s thanks to you that we are where we are, with three potential new partners in deep discussion. As I’ve been saying all along, pulling this off is still a longshot, but you’ve gone above and beyond the call in raising awareness and letting everyone out there know exactly how much Dark Matter means to you. And now we need you to pour it on for the big finish.
They are also able to discriminate between familiar individuals, and among humans. Cattle can tell the difference between familiar and unfamiliar animals of the same species (conspecifics). Studies show they behave less aggressively toward familiar individuals when they are forming a new group.  Calves can also discriminate between humans based on previous experience, as shown by approaching those who handled them positively and avoiding those who handled them aversively.  Although cattle can discriminate between humans by their faces alone, they also use other cues such as the color of clothes when these are available. 
The Gluteal and the Obturator nerves are the ones most affected; the latter more commonly affected than the former. The gluteal nerve is the nerve that controls the muscles to the buttocks. The obturator nerve runs along each side of the pelvic cavity to control the thigh muscles. If this nerve is damaged, the cow cannot pull her hind legs inward and underneath her to stand. Often one leg's more affected than the other, depending on which side she's lying on. Both legs may also be affected, resulting in her unable to get up without some kind of help. If only one leg is affected, she will be able to get up and stand (with a bit of encouragement), and stay up if the weaker leg can be kept from sliding out to the side. The gluteal nerve can also hinder a cow's efforts to get up, however if she does get up, she'll be a bit wobbly when she walks and possibly loose balance.
