Think of the following event: A collection of hieratic persons (from Harvard or some such place) lecture birds on how to fly. Imagine bald males in their sixties, dressed in black robes, officiating in a form of English that is full of jargon, with equations here and there for good measure. The bird flies. Wonderful confirmation! They rush to the department of ornithology to write books, articles, and reports stating that the bird has obeyed them, an impeccable causal inference. The Harvard Department of Ornithology is now indispensable for bird flying. It will get government research funds for its contribution.

Life is sacrifice and risk taking, and nothing that doesn't entail some moderate amount of the former, under the constraint of satisfying the latter, is close to what we can call life. If you do not undertake a risk of real harm, reparable or even potentially irreparable, from an adventure, it is not an adventure.
