Though we have advanced a lot in many aspects, we could still not find substitutes of natural things like oxygen, water, blood, etc. That is why they are so important aspects of human life.
Donating blood is equal to donating life to a person. Tough technology couldn’t help create a substitution for blood; it helped us create a greater and safer process of donation of blood. The process is always assured to make sure the safety of both the donor and the recipient.
Though blood donation is a voluntary process, many nations still buy blood form people to assure continuous supply for storage in emergency cases. Blood donation also provides health related benefits to the donors like preventing accumulation of toxic qualities and is also said to reduce risk of heart diseases.
Blood donation can be done by any person above 17 years with minimum weight of 110 pounds for every 56 days, up to 6 times a year.
