More unnecessary animal testing

So, I was just reading a book about goal setting and everything was just fine.  The book is deeply rooted in scientific evidence, but I had no clue how this evidence came to be.  I am just trying to do my best in life and make some improvements for myself, so how is it I keep coming across stuff like this!  I AM a card carrying PETA member, but I am not a crazy, insane, in-your-face activist like many of you might picture.

I had to take a break from the book and rethink things when I came across a paragraph about shocking dogs in cages at a Pennsylvania University.  Apparently the "scientists" are shocking the dogs repeatedly to determine at what point they will give up trying to get out of their cages.  They are trying to determine the difference between a dog that never gives up and ones that do and the length of time it takes in the ones that do.

I ask you, how could this EVER be ok?  How can anyone do this?  I understand the some great and some not-so-great advances medical science has delivered.  But, can someone please explain this one to me?

I got bored with this.

Here I am again.  It's Groundhog Day... every day like the next with minor insignificant variations.  I want a different life but I lost the will to try to change things anymore.  Somehow, I ended up at the ripe old age of 47 and have nothing to show of my existence.  I barely remember or have anything to say about the past 25 years.  I have settled for, at best, a life of mediocrity.  I have tried to change things and do things differently, but when it becomes difficult, I question my motifs and wonder what's the point.  Is any effort worth it?  What am I hoping to gain.  Most days, I just want everything to be over.
