Not Eating/Age?

I have a rescue beardie that I adopted about 10 years ago. He lives with another (female) in an outdoor aviary in the Arizona Desert. They have plenty of shade, a huge wading pool and all the sunshine you could ask for. I also shower them with the hose about 2-3 times a week in the summer.
I feed them superworms once a week and they also have a lot of native bugs crawling around that i know they munch on. I think it's mostly roaches, crickets and sow bugs.I also offer fresh veggies and fruit from time to time. They have lived together happily for about two year.
The male hasn't eaten in about a month. He has no other symptoms, loves his showers, basks in the sun, no marks or bites on him.
Is it possible at 10 that he is just coming to the end of his life?

Thank you in advance.

Hello,

Bless him, I would love to see a picture of him, plus, seeing the outdoor aviary would be great.
Has he brumated before? It may be that he is slowing down like a lot of them do but hopefully
that is all it is.
You could try to get a fecal done on him, to determine whether or not he has worms or parasites.
How do his fat pads look, on his head?

Thank you! I will get some pics of the aviary to you tomorrow. He doesn't seem to be brumating as he is still fairly active. He looks ok, but feels pretty light if I pick him up.
