A USC professor of molecular microbiology and immunology ​explains why takeout is likely safe and how to make it even safer from COVID-19.

Stay calm
Don't run (like other cats, attracted to motion)
Avoid bending down or crouching.
Stare them down (w/ bears, avoid eye contact but w/ lions...stare them down).
Raise voice and speak firmly
If they approach, show you are BIG--raise arms and trekking poles, open coat
Clap hands, throw stone/stick in general direction
If attack, fight for your life (not like w/ grizzly where you play dead) FIGHT!!!
Protect head and neck
Aim for face or throat

Perhaps a little crass to start, The Yankee Marshal offers a logical philosophy for those choosing to carry a firearm. Excellent points all!
