While genes and lifestyle play their respective role in the aging process, deeper research further delineates between the two. Living past 100 may be in the genes, says Scientific American. "A glance at your family tree may indicate whether you have a familial tendency toward longevity. Research suggests that exceptional longevity—living one to three decades beyond the average U.S. life span of approximately 80 years—runs strongly in families... Genetic factors can contribute to the degree of longevity in at least two important ways: An individual may inherit certain genetic variations that predispose him or her to disease that decreases longevity; other gene variants may confer disease resistance, thereby increasing it."

- Yes, there have been floaters in space. The early days of space exploration were a learning curve!
- Amazingly, you don't need gravity to digest food. Peristalsis, the process by which your throat and intestines squeeze themselves, actually moves food and water through your digestive system without gravity at all.

A growing body of research shows promising signs that the keto diet might be able to improve mental health.
- The keto diet is known to be an effective tool for weight loss, however its effects on mental health remain largely unclear.
- Recent studies suggests that the keto diet might be an effective tool for treating depression, and clearing up so-called "brain fog," though scientists caution more research is necessary before it can be recommended as a treatment.
- Any experiments with the keto diet are best done in conjunction with a doctor, considering some people face problems when transitioning to the low-carb diet.
