I was going to say as well, just the act of getting older means some things will be forgotten. The brain does not have an infinite store. And as you get older, there are many more things that you are responsible for, and therefore some things get sacrificed from your memory. That’s just fact.
It's just really sucks that of the things that can't be remembered is the important stuff, yet I can still remember the opening bit of the Canterbury Tales that was commited to memory in school some couple of decades ago. yes, I know there's a difference in memory types, but come on!
It isn't physically addictive but it is mentally addictive and in this regard it will affect different people differently. I personally found it quite difficult to stop, it took over 5 years. Regardless I support its legalisation.
That said, my friend, 10 years of life make you forgetful sometimes.
That's just called living.
