(CNN) -- Having spent 69 days trapped inside the San Jose mine in Chile before being rescued, Mario Sepulveda says, he is a changed man.
"I buried 40 years of my life down there, and I'm going to live a lot longer to be a new person," he said in a video conference hours after surfacing from half a mile underground.
Sepulveda, the second miner extracted from the mine, has advice for those who take undue risks in their lives.
"I think I have learned a lot of wonderful lessons about taking the good path in life," he said. "For those of you able to call your wives or your husbands, do so."
During the time he was trapped inside the mine, Sepulveda said, he saw both good and evil.
"I was with God, and I was with the devil. They fought, and God won," he said. Sepulveda said he grabbed God's hand and never doubted that he would be rescued.
Sepulveda praised the efforts of the rescue crews but argued for reforms in the mining industry.
"I think this country has to understand once and for all that we can make change. In the area of labor, we have make many changes," he said. "I think the owner has to give the tools so that the middle managers can bring changes in terms of labor. The middle managers cannot carry on like they have."
The rescued miner had high praise for the doctors and psychologists who aided the miners via videoconference.
"They gave us our lives back. It's incredible that with 700 meters between us, and not seeing us face-to-face, they revived us," he said.
With the world watching and the media attention at the mine intense, Sepulveda said he hoped to maintain a low-key profile now that they are being rescued.
"The only thing I ask personally is that you please not treat us like celebrities or journalists. I want to continue being treated like Mario Antonio Sepulveda Espinace, the worker, the miner. I love that, and I think that, in some shape, way or form, I want to continue working," he said.
Sepulveda was flanked by family members as he spoke.
"I'm very happy for all the beautiful things that were done for us," he said. "I'm very excited to be up here again."
