Blood donation after effects and horse riding news

The blood donation has taken it's toll on my body. It's been 3 days and I've been getting tired quite easily. My resting heart rate has increased by around 5bmp to keep up with the oxygen supply and I also needed to sleep more. I checked online that red blood cells take 4 weeks to replenish and it takes 8 weeks to restore the lost iron. I'm helping this by eating more meat. I've also developed a rash on my arm due to the antiseptic - will use a different one next time. Isn't this ironic?! I donated blood to help people and now I need to consume more meat to help with my own health. But I guess this is the unfortunate difference between humans and animals. In general, a person's life is in their own hands, but such cannot be said about animals especially ones raised for human usage (yes, usage is a good term). I can go on and on about this but I'll stop here. Some exciting news! For horse riding today, I decided to change my saddle from 17.5' to 17' to help with my leg positioning. A great idea because my positioning was much better and my instructor pointed out my riding to the others in the class so that they can learn from me. After this, she said that I can change from Intro Adult to Beginner Adult class! In the Beginner Adult class, people have 'mastered' the trot and are perfecting on their canter. I just started with cantering, so going into this class will be challenging but certainly exciting, can't wait!
