There are properly dumb ways to 'live life to fullest' - driving too fast, especially on bikes. Destructive addictive drugs and doing stupid stuff on those (psychedelics are mostly not those). And probably thousands more. On the other side, there are those who make you feel amazing every time you do it, and the real risks are minimal. One example - sport climbing. Facing fear of one's death, while being safely belayed on rope that can hold 2 tonnes of static load. Overcoming that fear. Backpacking around the developing (but not so much) world, an extremely rewarding experience every single time. I would add tons of social activities with good friends to this. Such a life won't feel 'wasted' in any measurable way, while being almost as safe as sitting at home reading books (and probably better for your eyesight).
