Adequate sleep and exercise are two good ways to improve lymphatic drainage.

Which is why it's just part of why it's crucial to not use one's old age as an excuse to laze around. That, and the fact that we're actively fighting against the body's natural impulse towards muscle loss past middle age, which leads to bone density loss.

I'm in my mid 40s and I started strength training 2 years ago. I cannot state how good I feel! Focusing on cardio in my 30s was good but I hated every second of it. This time around, seeing my muscles grow and feeling badass is waaaaaay more fun, even if I'm all sore the next day.

And I started doing it exactly because of what you said, to combat natural muscle and bone loss as we age. I don't wanna be an old frail person when I reach 60+.
