No its not, because its impossible to collect rain water
that has come off the roof without some dirt and stuff
like bird shit and leaves from the roof, quite apart from
what happens to it sitting in your tank between when it
came off the roof and you get some to add to your battery.

The problem is the lead carbonate. Not enough to matter tho.

Nope, because of whats on the roof and in the gutters dirt and bird shit
wise.

The difference is that the distilled water hasnt fallen thru thousands
of feet of air in small droplets.

Wouldn't dream of doing that. You might burst into tears
and that would be rather embarrasijng and someone might
claim I have breached community standards.

Trouble with that approach is that you can't
usually connect the thick battery leads to the
new battery until the new batter is where the
old battery still is.

Some tap water is quite hard and produces

Not normally enough to matter.
 
But some still have water from wells for their tap water.

Particularly as most don't add water to their car battery anymore with
sealed batterys.

It doesn't leach out of the plates, its boiled off when the battery
is still charged when it has been fully charged already.

That's wrong too.

There is no equilibrium involved. You presumably
mean that the dissolved stuff spread thruout the pool.

Utterly mangled all over again. Lead doesnt dissolve in
water enough to matter.

Corse the designers of car batterys have.

Trivial to test that by weighing the battery before and after.

The reality is that modern cars use sealed batterys and no one
adds any water to them anymore.

That's wrong. You don't get hydrogen when attempting
to start the car with a battery that is flat or can't deliver
the current the starter motor requires to turn the engine
over fast enough.

More chance of accidentally touching part of the body of the donor car
with the positive lead clamp.
 
& the donor has less outgassing

A, but for a different reason.

The reality is that there are no contaminants like that in the

No, because the battery doesn't gas unless it is being charged when
fully charged already and that won't be happening with either battery.

Its more complicated than that in reality because you wouldnt

For them, it is a logical consequence of hoarding food in a survival
mode. What goes in, must come out.

Medical research says that enlarged prostate is a direct consequence of
male hormone, much like male pattern baldness.
 
I haven't reached a state that I have problem passing urine but I can
sense that the passage is narrowing because it takes longer to empty the
bladder.
 
I have been experimenting with all sorts of herbal hair tonics for more
than ten years now. I am not bald yet, but like every man I am thinning
at the crown.
 
Finally I come back to think about dealing with the male hormone, the
alleged culprit of male pattern baldness and enlarged prostate. I found
out on the internet that soybean and the artificial sweetener "Stevia"
have female hormone effect. So I started using Stevia instead of
Sucralose, and eating a lot of tofu.
 
https://www.amazon.com/Now-Better-Stevia-Organic-Sweetener/dp/B005F9XFN0
 
I also make 1% Stevia water mixture as hair tonic to apply in my crown
area. I add 10% in volume isopropyl alcohol mainly as preservative. I
don't know if Stevia can rot in water but I imagine no bacteria can grow
in 10% IPA solution.
 
For tofu, I buy from Chinese supermarkets soft tofu in plastic buckets
that look like this photo:
 
https://cdn.shopify.com/s/files/1/0360/7035/9178/products/WeChatImage_20200414153015_500x_a8743a02-1633-437e-ab22-79f27427aa69.jpg
 
I empty all the water and refill with cold tap water everyday and keep
in the refrigerator.
 
You might be able to find soft tofu in small plastic flats of 4, or 6
cubes in normal supermarket but Chinese supermarkets also sell tofu in
bucket size plastic containers as shown in the above photo.
 
My way of eating this tofu is:
 
Put one cube in a 2 qt batter bowl like this
 
https://www.walmart.com/ip/Anchor-Hocking-Glass-Mixing-Batter-Bowl-with-Lid-2-Quart/163913120
 
Cut the tofu in the batter bowl with scissors vertically many times
without holding the tofu by hand. Then add some cooking oil and close
the lid. Put into microwave and nuke it.
 
The steam can escape from the lid so there is no danger of the steam and
pressure blowing the lid off in the microwave.
 
Season with anything you like, but I usually eat it with other food in
my meal.
 
It will take a long time to see results in countering the deleterious
effect of male hormone in man's hair and prostate, but I can tell than I
have less sex drive after two months of using Stevia as sweetener and
adding tofu to my diet. Maybe it is working.

They weren't hoarding food in survival mode.

No evidence that more would go in with covid around,
so no need for more toilet paper than usual.

Doesnt explain why an enlarged prostate shows up in old age
when the male hormone levels have clearly dropped significantly.
 
> I haven't reached a state that I have problem passing urine
 
I dont either and am almost into my 80s. Never need to piss at night
either.

Don't get any effect like that either.
 
And my PSA tests are fine.

I haven't bothered and have been visibly balding for more than 50 years
now.

I am much balder than that and it is genetic, my dad started
to thin in his 30 and ended up quite a bit balder than me.

Don't buy that claim with enlarged prostate for the reason I listed.
