They do not care if they have anything left for themselves but they only care about the ones that they are helping. They need to devote all their days and nights long of hard work to bring about a positive change in people and these animals that have been struck hard by the causalities in life.
This man spent years of his life in bringing up two gorilla babies who were unfortunate to have lost their mother at the time of their birth. Both of these gorillas were happy babies and they wanted the love and attention of this man like his own family and the man left no space for any complain whatsoever and just like a good parent when he saw that the gorillas have reached a certain age he made the toughest decision of his life to set them free on their own in the wild.
