Don't do that!  Your email contains headers like the following:

  In-Reply-To: <ccd8be491003232152u60ed0396wc01eecd00c2961de at mail.gmail.com>
  References: <b27b51081003232136p78bc6370iff946be9d162c07b at mail.gmail.com>

The message-id field contains a unique identifier for this message, the
in-reply-to refers to the previous message's message-id, and references
contains a set of previous message ids from the thread.

This is used by decent mail user agents (i.e. your mail reader program)
to 'thread' email.  If you use 'reply' when you want to start a new topic,
your message (and its replies) will be threaded together with the
original topic.

If I haven't seen further, it is by standing in the footprints of giants
