Transplanted hearts adjust their biological age to that of their host

So, I just read this fascinating study about heart transplants, and it turns out that donor hearts actually adapt to the biological age of the person receiving them. It is quite incredible to think that a heart from an older donor can essentially get a refresh inside a younger body, while younger hearts might age a bit faster in an older host. This research, which looked at both mice and human patients, suggests that we might be able to use organs from older donors more effectively than we thought before. Which brings me to the potential impact here, as this could really help shorten those long waiting lists for transplants. And here's the thing - it shows just how much our environment and our own bodies influence the organs we carry, which is just mind-blowing to me.
