None of us lives a life without risk. We make decisions, even those that may be considered unwise, by weighing up any potential risks and benefits associated with our actions and behaviours. We can usually be autonomous in our choices, and may dismiss the concerns of others, interpreting information to suit our own narrative because the perception of risk is subjective, as is the perception of well-being. Yet for people who lack mental capacity, decision-making is far less straightforward.
