Editing Life expectancy (section)

===Maximum===
[[Oldest people|The longest verified lifespan]] for any human is that of French woman [[Jeanne Calment]], who is verified as having lived to age 122 years, 164 days, between 21 February 1875 and 4 August 1997. This is referred to as the "[[maximum life span]]", which is the upper boundary of life, the maximum number of years any human is known to have lived. Although maximum life expectancy is around 125 years, genetic enhancements could allow humans to live for a maximum of 245 years,  according to InsideTracker.<ref name="Santrock">{{cite book|vauthors=Santrock J|date=2007|title=Life Expectancy.
