>> feel winded, but not short of breathe
I had anemia a few years ago. I imagine it's similar. Just not carrying enough oxygen around in the blood. Felt winded and chest pain. I thought maybe I was having heart problems.
>> training daily
What does that look like for you? That is, what type of training and how much. I try to do something most days (not every day though), but I need to mix it up a lot. It *should* include more strength training, but I enjoy running trails too much.
My latest thing the last couple weeks is playing catch. The 7yo up the street suddenly became obsessed with baseball and we play catch. He even got me a glove because he dad is a leftie, so I can't borrow his dad's glove. I told him I hadn't worn a baseball glove in 49 years. I made a good running catch and he said, "You've improved since you were nine." I told him, "Hey, maybe I was really good when I was nine" (I wasn't).
Anyway after a lifetime of ranking baseball as one of my least favorite sports to watch or play, I find tossing a ball around with a kid for an evening is a great way to loosen up at the end of the day. And he really appreciates it. He is now set on making it to the Majors
