Yeah, this 'flatten the curve' advice is the real deal. Here in Alberta, Canada we started adopting social distancing from the minute we had a confirmed case. We still see new cases every day, but it's linear. In the US right now the number of cases doubles every 2 or 3 days. Without taking big steps to stop the spread, you're looking at a grim outlook a month from now. I understand that if you're outside the high risk population this might seem like an overreaction, but if you have elderly parents, grand parents, or know anyone with health problems you should be doing it for them.
I have a solid home gym (bike, rower, power rack and olympic bars, 500lbs of plates, bowflex adjustable dumbells, plenty of floor space, wall mounted TV), so I'm lucky not to be too impacted on the fitness front. I've still been out XC skiing and mounting biking though. I think that still counts as social distancing since I almost never see anyone else out there when I am.
