This ain’t a song for the broken-hearted
No silent prayer for the faith-departed
I ain’t gonna be just a face in the crowd
You’re gonna hear my voice
When I shout it out loud
[Chorus:]
It’s my life
It’s now or never
I ain’t gonna live forever
I just want to live while I’m alive
(It’s my life)
My heart is like an open highway
Like Frankie said
I did it my way
I just wanna live while I’m alive
It’s my life
This is for the ones who stood their ground
For Tommy and Gina who never backed down
Tomorrow’s getting harder make no mistake
Luck ain’t even lucky
Got to make your own breaks
[Chorus:]
It’s my life
And it’s now or never
I ain’t gonna live forever
I just want to live while I’m alive
(It’s my life)
My heart is like an open highway
Like Frankie said
I did it my way
I just want to live while I’m alive
‘Cause it’s my life
Better stand tall when they’re calling you out
Don’t bend, don’t break, baby, don’t back down
The attached video is of dolphins playing with silver colored rings which they have the ability to make under water to play with. It isn’t known how they learn this, or if it’s an inbred ability.
The dolphin does a quick flip of its head and a silver ring appears in front of its pointed beak. The ring is a solid, donut shaped bubble about 2-ft across, yet it doesn’t rise to the surface of the water. The dolphin then pulls a small silver donut from the larger one. Looking at the twisting ring for one last time a bite is taken from it, causing the small ring to collapse into a thousands of tiny bubbles which head upward towards the water’s surface. After a few moments the dolphin creates another ring to play with. There also seems to be a separate mechanism for producing small rings, which a dolphin can accomplish by a quick flip of its head.
An explanation of how dolphins make these silver rings is that they are “air-core vortex rings”. Invisible, spinning vortices in the water are generated from the tip of a dolphin’s dorsal fin when it is moving rapidly and turning. When dolphins break the line, the ends are drawn together into a closed ring. The higher velocity fluid around the core of the vortex is at a lower pressure than the fluid circulating farther away. Air is injected into the rings via bubbles released from the dolphin’s blowhole. The energy of the water vortex is enough to keep the bubbles from rising for a reasonably few seconds of play time.
身涉艺术、设计的（我不说“搞艺术的”，因为“搞”这字眼很难听），常会说：“Ａrt is subjective; Design is subjective”，什么“各花入各眼”之类的。对此，我是颇不以为然的。Art和Design确实是有所谓的“subjectivity”成分，但那subjectivity不过是个人的偏好（preferences），对某幅作品的欣赏仍建立在objective的基础上，例：“我不喜欢这幅画，但我不否认这幅画画得真不错。”
