Subject: Limits of human life span

Remark to: #14571: No limit on human lifespans? [Corbally]
Nobody is able to remove soot particles out of  human lung tissues,
prevent scarring or replace brain cells or renal corpuscles totally (at
least before development of nanotechnologies). Therefore the human
lifespan is limited but their length may be open to some extend.
However, some organs seem to reach their limits around 100 years of age
(e.g. the eye lens, lacking cell replacement, and the elastic systems of
the respiratory system).
