There are multifarious factors checked and rechecked when locating a suitable donor for any organ. If somehow a person did manage to leave that somehow perfectly healthy life, their lungs very well could be young and healthy enough to last an extended period of time. The age in years is not always a good indicator on the actual health or remaining longevity of a particular organ(s) in the body.

Again, the greatest issue comes from the use of drugs that stop the donor recipient's body from attacking the donated organ. Sometimes infections can arise that we would not see in otherwise healthy individuals.

Other side effects can also manifest though despite these, many people feel the opportunity to live longer amongst their family and community far outweighs the risks and side effects of an organ transplant.
