He's got the heart of a champ! Coming back from having a layoff due to cancer and winning by knockout! Hope all the best for Danny.
The fact that he even got in the ring is a miracle that demonstrated incredible tenacity. And just think: When he lost to Pirog, 90% of ESB posters declared him a bum. Think about it!!
He is probably cancer free, but actually it takes five years to be declared cured(unofficial, but I think some companies here will sell you life insurance after 5 years.). But even then... It is not uncommon to have a relapse, even after 5 cancer free years. My sister's came back, with a vengeance, after a little over 5 years.
