(correction please) A life without risk is a boring life.

I disagree with this statement. I think it depends on the personality of each person. Some people have a very exciting life and others think it is boring. A person who is quieter, more bohemian and calm, will probably like to live in this peaceful way and don’t looking doesn't look for risky actions (or "doesn't need risky situations"). Instead, a more adventurous, daring and restless person, may need to do things that give excitement to his/her life. So, I think that each person has a concept of life and others may think otherwise because they are different.

(I agree Raquel! Also, great job :) You expressed your ideas and opinions well.)
