i think they should have two kinds of lessons
one is the usual one we always have, unprepared, unaided
the second one is for more professional first aider
especially for those who always organise events, marathons
etc
frankly, mouth to mouth, feeling for heartbeat shouldnt be worse
just because we dont have gadgets

purpose, you may not know the injured illness..and secondly,
computerisation gives you a better diagnosis. Well, time changed.
Maybe these people who make the gadgets are trying to make money
out of it.
