So as not to sound like a eugenics question, I‘m not talking about taking people and changing either them or their offspring. I‘m talking about designing a new strain of human that would be a species in its own right, with all the kinks and quirks and such cleared from their DNA (such as congenital diabetis or a tendency towards low immune system function).I‘m not really thinking of anything that would look too different, the major changes would all be on the inside. However, if there are structrual differences you think should be made, go ahead and run wild with it.One thing I think I‘d do is to make each of the various physical senses not only sharper and more efficient, but also able to be switched on and off at will (I learned to appreciate silence when I had ear problems some time back, and in many ways still miss being able to just shut off the hearing aids and enter my own little world).
A redesign of the spine for a start. It was originally designed as a suspension system for horizontal body position (quadrupedal movement) and it hasn't really gotten all the kinks out when it comes to bipedal movement. Hence all the back pain.
I'd redesign all female parts. Totally. And I'd put valves in the ankles, so when we need to lose weight, we just open a little tap and it drips out. And our teeth would renew, like a shark's. And our hair wouldn't grow so long. And my teenagers would have zips in their mouths!
Green spots on copper are the equivalent to rust on iron. This happens more often where solder paste has run onto areas of the pipe (as previous answer). One more caution, if there is an actual leak, you will see a small drop appear at a specific spot and then when it gets big enough it runs down the pipe. Sweating will be more area general. Leaks can happen particularly on ageing thin wall copper pipes. If so replace the pipe.
For the best answers, search on this site shorturl.im/awAIs Oxides of copper are all green. Any copper exposed to the environment will oxidize and eventually will turn greenish. The reason why SOME copper does NOT oxidize is because it is coated with a clear plastic or paint, which separates the base metal from the air and means no corrosion. The same applies to every metal. All metals form oxides on the surface. Some metals like iron and copper are obvious as you can see the oxide after a while. Others like gold, not so obvious. The oxide layer is either tightly bound and separates the base metal from the environment or porous which does not separate the metal from the environment. Gold is tightly bound and so thin you can see through it. Red rust is porous. Copper is sort of half way in between, forming a semi-porous layer which after a while gets thick enough to separate the metal from the environment and stop the corrosion from going any further, like applying several layers of paint when one layer or two is not enough to cover the existing color. ALL copper buried in the ground is coated to prevent corrosion. In your case, that coating was damaged in places, and everywhere it was damaged, copper oxide formed and turned the damaged spot green. Someone, probably not a professional as a professional would KNOW to be careful of the coating, was not very careful when installing the copper pipe, so it is possible you should worry. If you look closely, I'll bet you see actual damage to the copper under the oxide where it was dinged or scraped in some manner.
Addressing the kinks and quirks being related to DNA as cause of disease, I believe that this is a false assumption. Man started with just a very few basic diseases, four is the range I am describing, way back when life was simpler. There are now well over 40,000 offshoots and all exist within our bodies simultaneously as potentialities. So what happened is that when we learn to deal with one another pops up. That is because we are built with a system of checks and balances and that system is related to our thinking processes, intellectual, instinctive, and emotional mainly. Plug one leak and another two are created. Yet in spite of this and likely because of this, modern man lives longer, grows taller etc., and this is evolution. There are always more ways to skin a cat, as we used to say. Once again I repeat; we are designed for expansion and that is propelled by desire which is propelled by the negatives, such as illness and disease, as well as emotions such boredom. Eventually we get around to allowing which is the third force in the growth process and the cycle restarts itself. Energy always needs to flow. All is well in the long run. Cheers !!
