An acquaintance, a decade ago, took about 5y off to go on a world tour. When he returned to London, his skills were so stale, he couldn't find anything.
After 6mth of hunting in vain, he wrote a CV focussed on his oldest skill -- Fortran -- and found a role in weeks. When he told me this, he'd been renewed 5 times and had been in a 6mth role for nearly 3 years. He suspected he'd be doing it for the rest of his working life.
I got a bunch of interviews around 2010-2011 for DEC OpenVMS sysadmin work. I do have VMS skills, but not high-level ones -- but companies were having real problems finding people to maintain their Alpha and Itanium servers. The demand was there.
