BMGsmille say :

I do not think we can begin to say a line is healthy or not because we will never the true story of how the ancestors died. There are to many variables and one of the most important is that we learn from our mistakes and things progress as a natural order of life just as things die as a natural order of life. After all we have learned things that are bad for us and yet we still do it for me it is smoking but yet I still do it and we still continue to breed

Bmgsmille ,
believe me, Raimbow Bridge don't exist in reality. In reality they died youngs and this is NOT soo nice.....In reality when one creature died, he can eliminate urine even he was champion !
Nothing GREAT ....such many try to say

What we can do now ? Not soo much...unfortunately.
But the truth must to be sayed and responsable mans for actual system must to PAY their errors.
