What's the Risk?

I was 99% sure this was a Spring Amanita (A. velosa), which is delicious. However, getting this particular identification wrong would have meant my last meal. This mushroom has two look-a-likes - apparently just as tasty, but eating one is one too many. So I decided to throw this little fellow back under the tree where I found it. 

It's important to know if you're deciding on an option that looks delicious, but is possibly deadly poisonous. However, most decisions in life aren't quite that risky.
 

What if that thing you want to do won't kill you if you're wrong?
