Your lungs mature by the time you are about 20-25 years old. After about the age of 35 , it is normal for your lung function to decline gradually as you age. This can make breathing slightly more difficult as you get older.
Does vital capacity decrease with age?

After about 35, their function declines as you age and as a result, breathing can slowly become more difficult over time.
What causes a decrease in vital capacity?
The cause of a reduction in VC can often be inferred by analysis of maximal expiratory flow . Abnormally decreased flows support the diagnosis of an obstructive ventilatory defect, suggesting that the decreased VC is due to an increased RV (as in asthma, chronic bronchitis, and emphysema).
