A shout-out to all first responders. I am three months short of turning 90, and even though I try to exercise daily inside the house I am losing muscle tone. Yesterday I thought some fresh air and sunshine might be good for me, so I took a short walk. I was almost back home when a gust of wind caused me to lose my balance. I let myself down gently to the pavement to keep from falling, then found that I was too weak to get back up. I called 911; they sent two policemen who helped me up and escorted me back to the house. First responders deserve our praise, especially in these crazy times.
