Ya I believe most of us feel that way. DA is a car crash. Whats he's doing now with his body is most likely worse than what he did to get in the position he's in today. And it seems the sicker he gets, the more tattoos and more oil go into his body. The ego is a powerful force for sure...
It is possible that with kidney failure and being on dialysis, DA isn't able to lift as he once did. Rather then watch his muscles wasting away, he compensates by shooting oil into himself. The changes in his facial structure is concerning. It doesn't appear to be part of a normal aging process, but perhaps a result of his poor health. He is also always wearing a hat lately. Is it possible he's lost his hair? Sometimes when people are seriously ill, there hair falls out.
Seeing how he looks today verses how he looked just a few years ago, is very sad. It must be hard for him to look at himself in the mirror.
