the Doctor's emphasis on first aid is understandable. He's a doctor! If you start "camp robbing" item A to supplement item B, when you need to use A for it's dedicated purpose it's depleted. I carry a seperate first aid kit. My pocket tin has a duplicate; one for survival and one for first aid and so on up to the house supplies. I don't like the idea of rummaging through matches and snare wire to get at sting ointment. My pocket kit is peened with a cross painted red. No mistaking boxes in a hurry or the dark.
