I'm 38yo (39 in September). Around the 2nd or 3rd of January I was walking to the shop and for some bizarre reason I suddenly realised I will be 40 next year!
Also in 3.5 years time I have lived away from Middlesbrough for the same amount of time I have lived away, I also still say I'm from Middlesbrough if anybody asks(get asked fairly regularly because of my accent) even though I spent about 12 years in Lincolnshire and spent nearly 6 years in Essex I don't really feel any affiliation with either area.
