A May 2021 study by the Institute of Functional Medicine said,
"Advanced age is the largest risk factor for impaired mental and physical function and many non-communicable diseases including cancer, neurodegeneration, type 2 diabetes, and cardiovascular disease."
"It may be that emerging 'omics' approaches continue to evolve our understanding of biological age prediction and reversal beyond DNA methylation alone. Integration of our future understanding of multi-omics data should therefore be considered in the future trials of candidate age-delaying interventions."
