    Write a function that activates all even-positioned health indicators in a patient's binary risk score, where each even bit represents a specific medical condition or risk factor that requires monitoring. The function should set all even bits to 1 while preserving the original values of odd-positioned bits, enabling healthcare providers to identify comprehensive risk patterns in patient records.
