A concept known as "heart age" may be used to predict stroke risk, with some outlets suggesting that a person's heart can be older than their actual age. An ai tool is reported to be able to measure heart age, and doctors are warning of the risks associated with having a heart age that exceeds one's chronological age, potentially due to factors such as obesity. The relationship between heart age and overall heart health is being discussed, with some reports focusing on lifestyle changes that can help mitigate the risk of heart disease.
