So you& #39;ve decided to start wearing a mask when you go out because of #COVID19 ? OK. But don& #39;t be half-assed about it. Wear your mask properly, or don& #39;t wear it at all.
Here& #39;s a thread, thanks to https://www.nytimes.com/2020/04/08/well/live/coronavirus-face-mask-mistakes.html 
What& #39;s">https://www.nytimes.com/2020/04/0... wrong with this?

Mask/2 #COVID19
Figured that out? (He didn& #39;t over his nose.)

What& #39;s wrong with this mask-wearing?

Mask/3 #COVID19
Get what she did wrong? (Didn& #39;t cover her chin.)

How about this one? It& #39;s probably the most common mistake I see around NYC.

Mask/4 #COVID19
See what he& #39;s doing wrong? (Tighten it up so that the mask sides aren& #39;t open and sloppy -- nice viral entry points.)

What& #39;s wrong here? (Tricky one.)

Masks/5 #COVID19
Seems ok, right? But no -- she& #39;s only covering the tip of her nose, leaving open space on top -- needs to pull the mask up and under her glasses.

How are you doing so far?

Here& #39;s another one -- see it?

Masks/6 #COVID19
It& #39;s an obviously useless way to wear a mask, but I counted 3 people "using a mask" this way in my quick grocery walk today. Also easy cross-contamination opps as you tug it up & down w/contaminated hands.

Finally, anything wrong here?
(Nope: This is perfect.)
