Disappointed with my brother's HVAC habits

I don’t understand what goes on in my brother’s head.

He is not the cleanest person in the world, he loves to be lazy and he always eats out.

He wonders why he is always miserable and he always complains that he doesn’t feel great. I wish he just took better care of himself and actually woke up and try to live life and what’s the saying, “Get outside and touch the grass.” He doesn’t do anything and he is proud of his many hours spent online laughing with friends and saying how great he is at shooter games. I don’t understand what is so spectacular about video games anyways. I just love going to the beach and having bonfires with friends. The reason he is sick all the time is because he needs to change his air filters. The air quality in his place is garbage, that’s the easiest way I can say it. I’m not going to beat around the bush about it. It’s all facts and he knows it. Our buddy, Timmy works for the HVAC company and looked at it one day and said that he needed new ones and he should go out and buy them. Do you know what my brother did? He went out and bought a new video game instead of taking care of the air filter problem. There is nothing that can make this guy take care of himself and he just doesn’t care. Maybe for his birthday, I’ll buy him air filters and then install them for him. I know he won’t do it.
