   • 2024 June 20, Eva Corlett, “Fidlets, fingies and riding a doo: study sheds light on Antarctic English slang”, in The Guardian‎^[1]:

     “It’s possible when we started building research stations in the 50s and 60s words like ‘boondoggle’ might have been common at that time and it became a regular part of speech … in Antarctic culture it can take on a life of its own.”

2. A range of the numbers fifty (50) to fifty-nine (59).

   No way you're in your 50s! I find that hard to believe.

   Temperatures today will range from the low to high 50s.
