Re: cell split and death

[Jerry Zhu <***>]

When cells divide they are no longer there only
becomes new ones.  Parents cells do not die.  They
become childern cells themselves. I think cells split
at later age.  Age is measured by energy level stored
in cells.  My estimate is that cells die at early
stage in similar way babies die. They can not make it
into adults. This proposition can be observed
experimentally.  There might be research being done
showing when cells disintegrate.  To my estimates,
energy plays important role in the process.
