Being the age of 42 doesn't mean that you're old. In fact, you are your best in life at that age because you're established in your career. Madsen isn't giving himself enough credit. In your 40's, you have a lot of wisdom that you can pass on to other people. Young people are not wise.
Yes, I think that our culture focuses on youth and beauty way too much. We are all going to age unless we die, so we need to start thinking of it as a positive thing instead of a negative one. In many cultures, the eldery are revered and respected, and we need to get back to that.
We're wired to think positively about young beautiful people. We notice them, we spotlight them. I do think we're too focused on the appearance part. There are more important things than looks, but it's much easier to get along in the world if you're pretty. It's also an advantage when looking for jobs, friends, partners etc. We need to learn to look past the superficial, but it's not easy.
It is not that we focus on the youth and beauty too much, but that we're more socially aware in our society now. Everything is online by Facebook, Instagram, Twitter, Snap Chat...etc. Because we're more aware of things now and much quicker, it only seems that we're focusing on it more. The days are long gone when we discovered something much later. Everything is instant now. It gives us the luxury to discuss it instantly and perhaps we’re more aware than we might be otherwise. Because we now have the opportunity to engage in that way it only gives the appearance that we focus on it more. If we actually focused more on the youth and their beauty, then perhaps there would be less bullying in our society. Clearly that has not occurred.
