Are you looking for something interested? Would you like to give a hand to other people in your spare time? Then joining us and be a volunteer! We have job for people of all ages. Anyone from students to old people can
become ours members. You can help people in many ways. Some schools need volunteers to help take the care of children. Volunteers are needed in hospitals help the patients. Animal lovers can help save dogs and cats
without homes. There is nothing for everyone."I often played computer games when I was freely before. Now
I help old people learn to use computers," said a volunteer aged 18. Unless everyone helps out a bit, we'll all have better and warmer world to live in.
