What is the longest nerve cell in humans where is it and how long is it?
The longest axons in the human body are those of the sciatic nerve, which run from the base of the spinal cord to the big toe of each foot. The diameter of axons is also variable. Most individual axons are microscopic in diameter (typically about one micrometer (µm) across).

Why we age and die?
Methylation of DNA slows over time, which creates an aging biomarker, so if we measure how much DNA of an individual has been methylated, we can estimate their biological age. Some genes may also become hypermethylated with age causing them to loose function, such as the estrogen receptor.
