I partially agree. Most items do not need to be directly on you. Most just need to be handy. Many are not needed at all.

Fish hooks and storm matches may be of little value below 72nd St. But a couple of bandaids and Tylenol in a small FAK, spare Metrocard, and emergency cash may be of great importance. A safety pin might be nice if you pop a button. As well as the whistle, small knife and photon. An evacu-8 hood might serve one well also.

Most of these items can be left in a briefcase until needed. You probably wont need that asprin immediately.
