You’re brushing your teeth and notice your arm looks thinner than last year.
You stand up from the couch and your knees creak like old floorboards.
Carrying the groceries leaves you winded in a way it never used to.

That’s sarcopenia — the silent muscle robbery that starts around 50 and accelerates after 60.
Left unchecked, it steals 3–8 % of your muscle every decade… until one day a simple fall changes everything.
