Signs that I am feeling my age in my mid-50s

‌I've been feeling the aging process lately. It's quite a heavy feeling. I'm trying to age gracefully.
1. Food gets stuck in my teeth a lot.
2. Even after showering in the morning, I notice an odor by the afternoon after lunch. It's not a sweat smell, but more of a scalp odor?
3. Foot odor or hormonal odors seem to disappear.
4. Slight forgetfulness sets in.
5. I feel a loss of muscle mass in my thighs and elsewhere. Even with consistent exercise, it's the same.
6. It's nothing special, but I find myself tearing up when watching emotional content.
7. My movements become less agile. That sense of quickness is gone.
8. Understanding diagrams or explanations becomes very slow. I can't grasp them at a glance anymore.
9. Libido almost disappears. Instead, focus on work increases, though efficiency actually drops.
10. I no longer mind spending money on my wife or children. Instead, I find myself cutting back on my own expenses.
and so on.
It's already been well over 20 years of living on M-Pact; I hope everyone ages happily!
