Christy Knowings, the former All That star, died at 46 from cardiac arrest following a severe asthma attack that left her brain-damaged; the death certificate lists asthma as the underlying cause with acute hypoxic respiratory failure and status asthmaticus among contributing conditions. Tributes from peers like Kenan Thompson followed, and Knowings later appeared on Sesame Street with her twin brother Chris Knowings.
