Aging Research

Anti-aging therapies may help more people approach a natural lifespan boundary without removing that boundary. Scientists disagree about how to slow aging and extend healthspan. Anti-aging science does not currently have expert consensus. Anti-aging science is still an emerging field without definitive answers to core questions. Animal life-extension experiments suggest lifespan can be biologically altered. The lifespan-limit estimate is said to support theories that presume biological limits to lifespan. Direct translation of gene modification and dietary restriction to human lifespan extension is limited by practical, usefulness, and ethical concerns. The findings are presented as supporting aging research that recognizes a possible natural lifespan boundary.
