Supposedly. Perhaps in body but not in spirit.

Grounding the fence should have been a given at least for the safety factor being a airbase.

All the time. Will definitely get your attentions. Yikes!

Plug your thing into 120v for a 60 cycle hummer!

Capacitance of Human Body What it shows: Determine the capacitance of the human body as follows. Charge a person of unkown capacitance to 1000 volts. The person is subsequently connected (in parallel) to an external capacitor of known capacitance. The voltage measured across the capacitor combination allows one to determine the unknown capacitance of the person (typically between 180 200 pF). https://sciencedemonstrations.fas.harvard.edu/presentations/capacitance-human-body Body capacitance is the physical property of the human body that has it act as a capacitor. Like any other electrically-conductive object, a human body can store electric charge if insulated. The actual amount of capacitance varies with the surroundings; it would be low when standing on top of a pole with nothing nearby, but high when leaning against an insulated, but grounded large metal surface, such as a household refrigerator, or a metal wall in a factory. Synthetic fabrics and friction can charge a human body to about 3 kV. Low potentials may not have any notable effect, but some electronic devices can be damaged by modest voltages of 100 volts. Electronics factories are very careful to prevent people from becoming charged up. A whole branch of the electronics industry deals with preventing static charge build-up and protecting products against electrostatic discharge. Notably, a combination of footwear with some sole materials, low humidity, and a dry carpet (synthetic fiber in particular) can cause footsteps to charge a person's body capacitance to as much as a few tens of kilovolts with respect to the earth. The human and surroundings then constitute a highly charged capacitor. A close approach to any conductive object connected to earth (ground) can create a shock, even a visible spark. Body capacitance was a significant nuisance when tuning the earliest radios; touching a tuning knob would couple the body capacitance into the tuning circuit, slightly changing its resonant frequency. However, body capacitance is very useful in the Theremin, a musical instrument in which it causes slight frequency shifts of the instrument's internal oscillators. One of them changes pitch, and the other causes loudness (volume) to change smoothly between silence and full amount. Capacitance of a human body in normal surroundings is typically in the tens to low hundreds of picofarads, which is small by typical electronic standards. While humans are much larger than typical electronic components, they are also mostly separated by significant distance from other conductive objects. Although the occasional static shock can be startling and even unpleasant, the amount of stored energy is relatively low, and won't harm a healthy person. The Human Body Model for capacitance, as defined by the Electrostatic Discharge Association (ESDA) is a 100pF capacitor in series with a 1.5kΩ resistor[1]. https://en.wikipedia.org/wiki/Body_capacitance An object that is made of conductors allows charges to transfer across the whole object. Materials that conduct ions, protons or electrons are capable of transferring electricity. Materials that conduct heat are thermal conductors. Those materials that conduct both heat and electricity include silver and gold. The human body is considered a conductor because when it gets a static charge, it distributes the charge throughout the body. https://www.reference.com/science/examples-conductors-adac473aedbcdaa6 Human Cell Walls as Capacitors https://www.physicsforums.com/threads/human-cell-walls-as-capacitors.927097/

I was grounded many times during my formative years and hated it. That said I am probably A better person because of it.

*** Going barefoot was just a normal part of being a kid in the southern latitude states; Georgia, Texas, and such ***
My Mom told us if we went barefoot we”d get hookworms.

We kids all went barefoot in Hawaii 65 years ago. I don't see the same in today's Hawaiian videos.
I've taken barefoot up again since retiring in Florida 20 years agoand feel especially good about it. It's like I've "grounded" with a distant past.
It's so "grounded", I sometimes have to remind myself to put my shoes on when about to drive into town!

re: “Capacitance of Human Body What it shows ...”
TL;DR
Been there done that, doing it now (EVERY TIME I walk outside to ‘tune’ the vacuum variable cap on my 160 meter loop antenna) ... fingers near the tuning know change the tuning a slight bit ...
REMEMBER as a kid walking across the carpet and getting a shock (this is in WINTER, when RH is low)? Yeah ... did that too ..
EVER fool around with an electrometer - its a device that measures static charge built up as you just WALK across a floor with tennis shoes? Yeah .. done that too. Tribolectric effect; look it up.
Nothing new under the sun ...

Coral cuts & inserts bacteria, very difficult to heal and not quickly either.

I first heard about this concept about a year ago. I say it cant hurt. Its good to be out enjoying what Almighty God has created.
I went out after seeing your post and the mosquitoes drove me inside before I could kick off my sandals!

I agree, nothing new and known science. :)
