As we age, our appetites can also start to wane, like a sunset on a tropical island. It's not just because we're getting older and wiser, it's because our metabolism slows down, and our stomachs start to shrink. It's like, our bodies are saying, "Hey, I don't need as much food as I used to, I'm good with just a salad and a glass of wine!"
And, let's not forget about hormonal changes, like menopause or pregnancy, which can cause a loss of appetite, too. It's like, your hormones are doing the cha cha slide, and your appetite is like, "Uh, what's going on here?"
