A proverb meaning one cannot overcome the effects of aging — as you get older, you can't do things as you used to.
最近は疲れやすくて階段の上り下りも大変だ。寄る年波には勝てないね。
Lately I get tired easily and climbing stairs is hard. You can't beat the advancing years, can you?
昔は徹夜も平気だったが、今は無理だ。寄る年波には勝てないと実感する。
I used to be fine pulling all-nighters, but now I can't. I feel you can't fight aging.
医師からも『寄る年波には勝てない部分があります』と言われた。
The doctor also told me, 'There are aspects you simply can't beat with age.'
