History is part of my sense of identity. It's who my ancestors were and how they lived.

There are two small parts of history that I would regard as having 'economic' value.

Old weather and astronomical records, everything from Chinese records of comets, to the detailed logs of shipmasters, are very useful to those studying climate change and astronomy.

Knowing old wind, temperature and rainfall patterns is very valuable in working out the changes between then and now, and helping us predict what is likely in the future.
