A question about resistance in the human body

[Jodo]

Back in grade 10..,.( Oh my that was awhile back ) our electronics teacher passed around a multimeter and everyone measured their resistance ( a lead held in each hand, Fluke was set on infinite ).
All in the class measured between 700K and 800K approx. All except me that is. I measured 1.4M ohms.
Our teacher exclaimed ( Aha we have one ! ) I was then asked to take the meter home and test my dad. He also measured 1.4M ohms.

Next day in class I announced my results and at that point the teacher explained it is hereditary but he offered no explanation as to why ( note, only my Dad measured the same as me. My mom and sisters all had 700K ish ohms ).
Well 35 years later I still get the same reading but no one has ever given me a reason as to why.

Any thoughts?

Do you and your dad have unusually dry skin?

Not that I am aware of.

I have checked myself several times over the years and it remains fairly constant ( within 100K ohms )
As a side note, I have been blasted sooooo many times by 575V 3 phase power at the welding shop where I work they have now knicknamed me Fluke. ( They think I'm crazy but I have always quoted ohms law and stated after each shock...I only get half the shock as most...rofl ).

True story, one shock actually blew the the steel toe right out of my boot. We found the steel cap about 50 feet away in the machine shop. It was covered in arc marks just like my right hand which I was using to unplug a welding machine. My right arm felt like it had been run over by a steam roller haha

Thick, hard and dry skin will measure higher resistance.
Thin, soft and moist skin will measure lower resistance.

The frequency of hand washing, and the type of soap or detergent used will make a big difference. Those who work in a kitchen, or care for young children, will tend to wash their hands more often and so have more conductive skin. Those who do hard manual work with their hands will develop hard dry skin that resists blistering and so measures high resistance.

The obvious gender differences in employment must be separated from the epigenetic and genetically inherited skin characteristics.

The best way to keep boys away from water is to give them a bar of soap.

In a post from another thread ...

Long ago I heard reports of a couple of people who were more immune to electric shock than others, (but not to electrical burns). It was said that they had a double myelin sheath on their nerves.
Double myelin sheaths are found in nature, but I would like to know if there is any credible documentation of immunity to electric shock as a result.

Interesting. I know I do indeed get shocks but I have managed to walk away from all instances of contact with 575V. I watched an electrician in the late 80s grab 575V and he was put off work for 2 weeks medical compensation. I must now go Google myelin sheath!

Thanks so much for the replies folks

I tested between forefingers and got the 800,000.
Between cheek bones it was 3M
