Editing Free-radical theory of aging (section)

===Epigenetic oxidative redox shift===
Brewer proposed a theory which integrates the free radical theory of aging with the [[insulin]] signalling effects in aging.<ref name="Brewer GJ 2010 173–9">{{cite journal | author = Brewer GJ | year = 2010 | title = Epigenetic oxidative redox shift (EORS) theory of aging unifies the free radical and insulin signaling theories | journal = Experimental Gerontology | volume = 45 | issue = 3| pages = 173–9 | doi=10.1016/j.exger.2009.11.007| pmid = 19945522 | pmc = 2826600}}</ref> Brewer's theory suggests "sedentary behaviour associated with age triggers an oxidized [[redox]] shift and impaired mitochondrial function".<ref name="Brewer GJ 2010 173–9"/>  This mitochondrial impairment leads to more sedentary behaviour and accelerated aging.<ref name="Brewer GJ 2010 173–9"/>
