Humidity Data and the Zapping of my LCD Display

Sometimes the Radio Gods conspire against you.   Check out the chart above.  It shows relative humidity at my location.   I zapped my LCD display right around 2000 UTC on January 25, 2016.  That poor little LCD didn't stand a chance :-(

Right now relative humidity here is 79%.  No sparks now! 

I like the solution (!) proposed by Brendan, EI6IZ:

You can get an anti-static spray designed to treat carpet, upholstered furniture etc. This is a sensible thing to do if one tinkers with electronics and for the average hamshack a bottle will last for many years as it only needs to be applied lightly and infrequently.
For example

I give my car seat an occasional squirt in dry summers to stop the 'zap' when getting out on a dry day.
