Describe promising avenues to increase the human lifespan.
What will be an ideal response?
- Species have an upper limit for maximum lifespan, ranging from a single day to hundreds of years. Unlocking the genetic code that says "time to die" presumably can extend that upper limit.
- Telomere therapy seeks to lengthen telomeres and allow the replication of cell division to continue indefinitely.
- Some researchers are trying to "unlock" longevity genes' ability to overcome environmental challenges and physical adversity
- Efforts to reduce the emergence of free radicals by using antioxidant drugs have shown some promise.
- Restricting caloric intake may prolong longevity, although it just may seem like the days go on forever when you're hungry all the time.
- Replacing worn-out organs with transplants may be an avenue to prolong life.
