Is it possible that humans attract bad smells? i'm experiencing it. thought it to be an illusion, but people around me used to get irritated. if i go near sewage drain i start to smell like it. lot more like septic tank, cow dung, things burningsmell?

The basic answer is no: you cannot "attract" odors, and you cannot smell like a bad odor you experience yourself. Never ask someone "Do I smell like [the bad odor] we just experienced?" That's an excellent way to prompt them to say yes, when in fact nothing is abnormal. Speak with your doctor if this problem seems to continue; it likely is a psychological issue, not a physiologic one. Good luck.
