Ghislaine Boddington aspires to be interconnected with an AI digital companion that advises and supports her, keeps her healthy and represents her around the world. A twin that could live on after her death, or for as long as someone pays the subscription. In practical terms, a digital bio-twin is made up of continuously measured multiple biological signals from your body. These might include your heartbeat, breath, temperature and muscle tension, as well as food intake, exercise and mental health - all fed into an avatar body. By combining AI and, for example, scanning our bodies and faces, cloning our voice and mannerisms, our virtual twin will become more and more like us. In a journey that involves an MRI heart scan, dancing in a Belgium basement and a discussion about digital death, Ghislaine learns how to build her own digital twin.
