Did not know about the wigs, but makes sense.
Charles isn't in good health. It's pretty plain to see. He didn't seem to inherit his parents' hardy constitution, sadly for him.
he looked nice when he walked meghan down the aisle
I think Charles DOES want to be King at some point; I can see him on the throne for (maybe) a few years and then relinquish to William. He's been waiting a long time (thank God - love QEII), so I think he would like that position for a bit. My opinion of course!
. If M&H actually stay married that long, it'll kill M to watch all the pageantry and news surrounding Kate, she'd be green 
with envy.
It is! I'm probably reading too much into it, but I do think it shows that Charles is in a vulnerable position health wise, which William knows and therefore the protective embrace. It must be a relief to Charles to have at least one reliable grownup child acting like an adult, to lean on as he himself is growing old.
At the same time I need to add that I'm commenting on Charles et royal al as a family, with which I can easily emphatise. But I do not consent to Charles dabbling in self-proclaimed elitist world ruling over us plebs with his pals Schwab, Rothschilds, Gates and other hubris laden and God complexed 0.1%:ers.
From what I've read: He has serious back problems. He often has very swollen fingers which have been very noticeable on numerous public outings. There could be many reasons for this. But just by looking at recent pics, he's starting to look frail. Losing his father who must have been a heck of an imposing patriarch and then being betrayed publicly by his own son has probably taken much toll on him and no wonder.
