Brainteaser #1

It's been a long time since anyone post an entry so I'll be posting something to keep this blog going on. I'll be giving all of you something to think about, something like (iq, riddles, puzzles etc.) and if you have the answers, you could tell me in person or you could just mention it in the chatbox. I'll give out the answers in few days time. Anyone can answer it, old or young, ugly or beautiful, anyone...(note to administrator, if you don't allow this to be here or don't think it's suitable to be posted, you can delete it).Here goes the first one,

Die without me,
Never thank me,
Walk right through me,
Sometimes feel me,
Sometimes hear me,
Yet never speaking and never seen

Who am I?

Think carefully. The answer is logical so don't give me the answer, there's no answer.

Peace out
