As I get older, I think my teeth are turning yellow.

I didn't notice it much when I was young, but as I get older, I feel that my teeth are gradually becoming more yellow. I think the biggest factor is probably frequent coffee consumption. Do others also feel this way when they look at their teeth as they age? I've also heard that getting veneers can weaken the teeth, and I'm curious if that's true, as well as about the costs and satisfaction levels. I also want to smile brightly showing my teeth.
