Donating blood benefits you and not just in the generous way. Yes of course the main reason someone should donate blood is to try and help others but let’s not forget there are free cookies at the end that you are told to eat. When was the last time a medical professional told you to eat cookies? It’s also healthy for men not to be sexist but this is a biological fact to donate blood because it helps cleanse their blood of extra ingredients. To make matters better you also get a pretty cool bandage in the end which you can keep for as long as you want. So donate blood and you will reap the rewards and so will many other people.
