Sylvester Stallone and his ex-wife Sasha Czack have been missing their only son Sage for ages now. Sage was barely 36-year-old when he died in his studio city home on July 13th. This agonising loss will be felt for the rest of our lives. Sage was our first child and the centre of our universe and I am humbly begging for all to have my sons memory and soul left in peace, tmz.com quoted Sylvester as saying. When a parent loses a child there is no greater pain. Therefore I am imploring people to respect my talented sons memory and feel compassion for his loving mother Sasha, he said.
