Welcome to HCM.
It is nearly impossible to increase the height after this age.
But unfortunately, height can decrease after the age of 40 yrs, due to bone loss and vertebral
disc compression. Are you aware of this?
To prevent this to some extent, get hormone replacement
treatment soon after the menopause
Having said that, You can APPEAR TALLER by following simple methods like erect posture, high heel shoes etc.
Being healthy is more important in my opinion.
