I am one of 66 million people in the UK.
The answer is no, we have a few 100,000 per cell.Over millions of years of evolution although much has changed, they have not changed in size, because the size and structure represent a sweet spot for their function.

You could say that we have learned similarly in the building of batteries; replicating and combining small cells works much better than trying to create large cells.The body itself carries on the advantages of scaling.An organ contains some hundred billion cells and the body is made up of about 100 organs and limbs..

If we look more broadly into the living world, we can see that size and scale are really important factors in function, efficiency, and survival.Human beings are not accidentally the size we are.

We’re a size that allows us to travel long distances.
We developed in the Rift Valley in Africa, a landscape that was rapidly changing, in relative terms, creating new and diverse habitats.“Just because you push risk onto somebody else doesn't make risk go away.
We have to start opening up our eyes and stop pushing down responsibility onto somebody else.That's why we're so siloed.
Also, we can't keep automating inefficient processes.”.The global evolution of industrialised construction.
