COVID-19 Outbreak (Update: More than 2.9M cases and 132,313 deaths in US)

Governor of New Mexico just made wearing masks for all mandatory in public not just employees of businesses. How is that enforceable?
How is it constitutional to force someone to wear a particular piece of garment? Not saying I wouldn’t, when I leave, my mask is on but if you break it down, people are bing forced to wear something. I am curious what other think.
