^It depends what kind of "good looks" you have. For men, the "boyish" look will fade quickly (and it's those types that tend to
struggle with it), whereas if it's the rough/rugged good looks, that can go on longer.
In my experience its the "pretty boys" that tend to have problems once they start to grow older. Many guys in their late 30s/early 40s who still
dress like they're 21.. I feel bad for them
Plus, it's very rare that good looks last. More often than not they can fade.
And being smart at 70 will have led you to having a good job, leading to lots of money and/or a great pension. I think it would pay off
