 Metaverse is a rapidly growing technology that has attracted the attention of many stakeholders, including academics and industry professionals. It offers opportunities to extend existing applications into the metaverse environment, enhancing user experience and improving quality of service. Healthcare organizations are beginning to explore the potential of using the metaverse to provide better care and increase life expectancy. This paper discusses how digital anti-aging healthcare can be achieved by leveraging AI, BC, IoT, and digital twins in the metaverse environment. AI can analyze large-scale medical data and generate personalized treatment plans while BC creates a secure and transparent healthcare data ecosystem. IoT devices collect real-time data from patients, which is essential for effective treatment. Finally, digital twins can simulate the effects of treatments before they are administered, allowing for more accurate diagnoses and improved patient outcomes. These technologies have the potential to revolutionize the healthcare industry and enable a digital anti-aging process for its users.
