Someone said: 'There is no old age, there is, as there always was, just you."
I think there is no old age - it all depends on you!
It might be a challenge at times. It's easy to be young when you're twenty or thirty. But being young when you're fifty or sixty it's not that easy - but when you succeed it's a great achievement.
Not to mention what you have learned by experience, which is an invaluable treasure worth to share.
Put value on what you have to say and give and forget what the others might think.
