What can we do right now? Not nearly as much as I’d like! I’ve had day dreams about harvesting my own skill cells, growing them into stem cells, and then implanting them in my head to eliminate gray hair… all using common kitchen items… but as my doctor is fond of saying, “we aren’t there yet.” Here are some things we can do while waiting for science to solve the death problem:
- Avoid Carcinogens. Carcinogens cause cancer, which can kill you. Quit smoking and Wear sunblock, avoid air, food and water polluted by cancer causing agents. Minimize your radiation exposure.
- Change your patterns of consumption. Drink plenty of water. Avoid overindulgence. Consider a calorie-restriction or intermittent fasting diet. Enjoy fish such as salmon.
- Consume antioxidants. They decrease the chance of developing cancer. Drink lots of green tea. Eat non alkalized dark chocolate. Eat red grapes every day. Eat five fruits and veggies a day
- Reduce stress Have close relationships. Reduce causes of stress and depression in your life. Try not to be afraid. Be as passive and easy going as you can. Look on the bright side. Keep on working. Smile. It relieves stress and changes your attitude. Laugh and Hug! Have Purpose.
- Get yearly physical exams.
- Get regular exercise. Walking 2 miles-a-day cuts the risk of death almost in half!
- Educate yourself. This is a life long responsibility, as is exercise! One of the most consistent markers of longevity across the world, in all economic conditions is higher education.
- Develop a sleep schedule. It is not as important to get a certain number of hours of sleep, so much as it is to get the same amount of sleep, at the same time, day in and day out. Sleep gives your body a chance to heal and regenerate; having a stable sleeping routine will help your body take care of itself more easily.
- Use your mind. People who read and exercise their mind a lot tend to be less prone to Alzheimer’s.
- Support life extension and rejuvenation research. The SENS project is a good place to start.– Adapted from wikihow

Life defined as biologically immortal is still susceptible to causes of death besides aging, including disease and trauma… Notable immortal species include:
- Turritopsis nutricula, a jellyfish, after becoming a sexually mature adult, can transform itself back into a child (the polyp stage) using the cell conversion process of transdifferentiation. Turritopsis nutricula repeats this cycle, meaning that it may have an indefinite lifespan. Its immortal adaptation has allowed it to spread from its original habitat in the Caribbean to “all over the world”.
- Bacteria (as a colony) — Bacteria reproduce through cell division. A parent bacterium splits itself into two identical daughter cells. These daughter cells then split themselves in half. This process repeats, thus making the bacterium colony essentially immortal.
Recent research, however, suggests that even bacteria as a colony may eventually die since each succeeding generation is slightly smaller, weaker, and more likely to die than the previous.
- Hydra can be considered biologically immortal as they do not undergo senescence or aging.
- Bristlecone Pines are speculated to be potentially immortal; the oldest known living specimen is over 4800 years old.
