杨军挺过了老虎凳，最后为啥认罪/放弃上诉？

In their statement, Dr Yang's family and supporters said the "harsh conditions in the detention centre, including enforced sleep deprivation, erratic medication and being strapped to a tiger chair, have destroyed Yang's health" and that launching an appeal would just further delay the prospect of medical relief.

"First, there are no grounds to believe that the system that enabled Yang's sustained torture and fabricated the charges against him is capable of remedying the injustice of his sentence."

"Second, commencing an appeal would only delay the possibility of adequate and supervised medical care, after five years of inhumane treatment and abject medical neglect."
