With Pantera, we lived through so many trend-of-the-day situations - when grunge was huge, we were still a heavy metal band; when hip-hop started getting incorporated into metal, we stuck to our guns and remained a heavy metal band very purposefully.
That is who Barack Obama is - a person of admirable character - and that is who he has remained for me over these last four years. I have not agreed with his every decision, but never once have I seen him break his cool, lose his composure, or abandon his insightful perspective - even during the most serious and/or absurd national disasters.
We have a moral responsibility to save wild places like the arctic refuge for future generations, and that is why our country has remained committed to its protection for nearly 50 years.
If Nirvana had remained a small, underground punk rock band, Kurt Cobain would still be alive. And he'd probably be living in Seattle, getting kind of fat and balding, be relatively happy and producing records for other people.
After Hiroshima was bombed, I saw a photograph of the side of a house with the shadows of the people who had lived there burned into the wall from the intensity of the bomb. The people were gone, but their shadows remained.
Since we launched the original 'Pop Idol' in England, I've remained close with Simon Fuller. Working as executive producer on 'American idol' for its first seven years not only was an inspirational journey into the heart of American pop culture, it opened my eyes to the untapped potential of the incredibly dynamic young people in this world.
There's a theory about fame: the moment it strikes, it arrests development. Michael Jackson remained suspended in childhood, enjoying sleepovers and funfairs; Winona Ryder, an errant teen who dabbled in shoplifting and experimented with pills; George Clooney, a 30-year-old commitment-phobe, never quite ready yet to settle down.
Every batch of sperm represents an opportunity for genetic typos - called de novo mutations - to be passed on. A 20-year-old man and woman will each pass on about 20 de novo mutations to a baby they conceive. By the time the couple is 40, a woman's total has remained at 20, while a man's has jumped to 65 - and it keeps climbing from there.
The skyscraper style first advocated by Louis Sullivan - a tower of strongly vertical character with clear definitions among base, shaft, and crown - has remained remarkably consistent throughout the history of this building type.
Without education, we are weaker economically. Without economic power, we are weaker in terms of national security. No great military power has ever remained so without great economic power.
