There are additional parallels in the growth of mental time 
journey into past and future across the lifespan, both by way of preliminary emergence ( Busby &amp; Suddendorf 2005 ) and eventual decline ( Addis 
et al. 2008 ). The neural and cognitive evidence linking episodic memory to 
imagining the longer term is more and more recognized (e.g.
Hassabis &amp; Maguire 2009 ; Schacter &amp; Addis 2009 
).
