Describe a person who often helps others

I would like to talk about my neighbour, Mr. Henderson, who is genuinely the most selfless individual I have ever encountered. He is a retired schoolteacher in his seventies who lives just a few doors down from me in a quiet suburb of Manchester. He seems to be in a constant state of offering assistance to anyone within a five-mile radius. Almost every single day, you will find him doing something for someone else, whether it is pruning the overgrown hedges for the elderly couple next door or helping local students with their maths homework in the community centre. His motivation is purely altruistic; he simply believes that a neighbourhood functions best when people look out for one another. He often tells me that he finds retirement boring and prefers to keep his mind sharp by tackling the various problems others face. He has this remarkable way of making people feel that their troubles are manageable, offering a calm, steady hand whenever someone is overwhelmed. Personally, I hold Mr. Henderson in very high regard. Seeing him act so consistently with such grace and good humour has genuinely shifted my own perspective on community living. I used to be quite insular, keeping to myself, but his influence has encouraged me to be more proactive in checking on my own neighbours. He makes me feel that kindness is not just a moral obligation but a rewarding way to live, and I feel incredibly fortunate to have such an inspiring role model living right on my doorstep.
