I'm 47, already FI but not planning to RE for a year or so.
Live near Cambridge, family of 4 with two late teens, one off to university in a couple of months (fingers crossed.) I'm an engineer, my wife was a SAHM for about 15 years, now doing some occasional work, not enough to pay income tax though.
Just had a month on holiday and not used the internet or phone at all in that time, highly recommended!
