Leg pain from degenerative disc disease can also result if the nerve root is compressed. This happens because as the disc degenerates it shrinks and moves, and as a result, there is not as much room for the nerve roots. This is also known as foraminal stenosis. Leg pain from a compressed and inflamed nerve root is typically shooting and electric.
Altruistic behaviour is therefore the opposite of egoistic behaviour. It involves intention to help others when used of human behaviour, but the fact that some animal behaviour is judged to be altruistic indicates that there are two possible bases to a definition: intentionality, and behavioural effects.
[SAFC] Altruism is likely driven by empathyâour tendency to âresonateâ with the emotional and physical states of other people. [Wired]. When you understand and feel anotherâs feelings for yourself, you have empathy. Itâs often spoken of as a character attribute that people have to varying degrees. For example, if hearing a tragic news story makes you feel almost as if the story concerns you personally, you have the ability to empathize.
