Study: homeless adults in San Francisco are 16 times more likely to 'die suddenly'

Unhoused people face many dangers living on the streets, from unsanitary living conditions to problems getting enough food and limited health care options. A new study by UCSF found that homeless people in San Francisco are 16 times more likely to die suddenly than their housed peers, with causes of death linked to heart problems and substance abuse. KTVU's Heather Holmes speaks with Dr. Zian Tseng, Professor of Medicine at UCSF about the study's key findings and what can be done to improve quality of life.
