I have had a couple of friends attempt to donate blood recently who were turned away because the machines weren’t able to draw from them.
Tubing issues were blamed first.
Eventually, the staff told them they couldn’t donate because the flow was being blocked by clots.
In both arms.
These people are all under the age of 35, by the way. And were under the impression they had no health issues.
Well, I'm not sure about that but if it did run slower in older people wouldn't there be more blood clots in older people? I mean over and above the "normal"?
Older folks with precovid heart conditions may already be on blood thinners which ironically could be what’s saving them and allowing them to fly under the radar somewhat. It’s the healthy under 40 and under 30 crowd having life threatening heart illnesses that are sounding alarms as it should be. Pro athletes should be the healthiest specimens around and can’t even run up and down the court without risk. Some in their teens still.
Bromelain is a natural blood thinner.
