While running in the park this morning I saw a woman take a hard fall off of a bike and I stopped and joined two others to attend to her, get her to the side of the road, await medical assistance, etc. When I left I noticed a drop of her blood on my hand, she was bleeding pretty good from her chin where she hit the pavement. I washed it off immediately with the water I had with me, although I was a couple of miles from home so it was about another 45 minutes before I got in the shower for a full scrub.
Anything to be concerned about, do, keep an eye on?
Thanks.
