over the hill 

Reaching the average mid-point in life, which is age 40. Therefore 40th birthdays are generally thought of as making it "over the hill". You've gone up the hill for 40 years ⬆️ (healthy, youthful appearance, etc.), now 40 more years down the hill ⬇️ (decreasing health, loss of physical beauty, etc.)

My mom is gonna be over the hill this month, she's turning 40!
