Over the past few days I haven't felt like doing anything. And I mean bone-weary tired. I 'assumed' it was from fighting the bike out on the slab from the intense wind we've experienced lately. But a few days ago I got my shingles vaccination. Like many 'boomers who had chickenpox as a child, I have a risk of shingles, a very painful experience. My brother came down with it. YMMV, but check with your health provider. You might also want to receive this shot. Anyhoo, I just can't shake this "hungover" feeling. After my wife returned from several days OOT taking care of her mother, she commented on a bruise on my left tricep, the location of the shot. I cannot see that spot obviously, and never made the connection between the lethargy and the vaccination. While a minor but nagging condition, I'm going to follow up with the problem. Even our dogs lay around after shots. I just never made the connection. Take care of your health guys! If you blink your eyes, you will look up and find you are my age. Time is precious. I have seriously worked out since I was 27 years old, and it has paid dividends. Fourteen of the men I rode with, guys my age, have now died from poor health habits like over-eating, smoking and drinking. When people at the gym comment on my health I always ask them, "Which is more surprising? A 62 year old man that performs like I do, or a twenty year old who can't?" Research the vaccination, and then research a good gym in your area!
