#4. He's on borrowed time
The reality is that many Superstars in WWE are going to have a much shorter career than we anticipate. With regards to Daniel Bryan, it has been clear for a long time now that he's on borrowed time.
The fact that he was able to even make that comeback and achieve what he did speaks volumes of his mental strength but what he never told anyone apart from the necessary people is that he is likely on borrowed time.

He knows that there's only a certain extent up to which he can wrestle full time and stay healthy. At some point, it may catch up and Bryan knows that the longer he stays as a full-time wrestler, the higher the risk of him suffering a serious life-threatening injury.
As a result of this, two years is probably the window that he has given himself and WWE as his shelf-life as a full-time performer. If he goes beyond that, it could be argued that he would be pushing his luck.
We have seen many instances before of superstars going on way longer than they are physically capable of and in a few tragic instances, it ended sadly.
