Not saying anything that the others haven't already said, but maybe suggesting another way to think about it-
Remember that the airplane itself is quite happy in the spin. It can go on spinning all day without the loads increasing. That if there is enough sky for it to descend through. Spins are only dangerous because if they are allowed to carry on they end in the ground. The airplane doesn't know that, but you do.
Spins aren't dangerous. Letting them continue until you hit the ground is dangerous. So practice them high up and fly well when close to the ground so you don't spin.
