I am no animal expert, so consult an expert if you do need to do that for any reason.

If it's only as a food for thought, depending on the mammal you'd probably be fine unless whatever animal has a very prominent feature you need to worry about. Farm animals have prominent features (cow produce lots of milk, sheep produce lots of wool) that most likely unbalance things a lot compared to us. Other mammal like cats and dogs probably have a balance close enough that the variation between their RDA and ours should be fine.

If you look at anything other than mammals, things change drastically. Hollow bones and feathers in birds, cold blood and scales in lizards, etc... are probably much further away from us.

Again, not expert on this subject, consult an expert if you're planning on putting your dog on the same diet as yourself.

Every vitamin is used by bodies for some purpose. Depending on what a certain species has or do, you'll need more or less of certain vitamin.

Animals with "bigger" brain will usually require more energy to make it work. Animals with large, constantly growing claws/teeths will need certain vitamin to keep growing them. Animals with hot blood will need more food for their heat.

Everything has a use, and what your body can do decide how much of each you need in average.

Not everything scale that simply.

Let's go for one very simple issue: Chips. Chips can only be made so small for physics reason. We're currently making chips and motherboard so small we can't make them smaller and still have them function reliably. We're talking nano meter wide circuitry. You can almost count the wideness in terms of molecule. A single grain of dust can already cause malfunction in these kind of things.

Nanomachines (son) are still really far away from being an effective solution. And that's not talking about batteries autonomy on these things.

Fortunately enough, eyes are quite resilient. It takes a decent amount of damage to permanently alter vision.

Which is also frightening when you consider how many people hurt their eyes on the daily watching a screen (me included)

Didn't know that one. Thanks

What happens when you jump? You flex your legs and push the ground really hard. Eventually, you get away from the ground.

But why? You pushed DOWN, against the ground. How come you're going UP? That's Newton's 3rd law. As you're pushing the ground, it is also pushing against you. Since usually the ground is much heavier than you, it barely move if at all, while you move a lot more.
