Yes. I did a lots of stamp collection when I was a kid. But the problem that I had faced that it was hard to know the worthiness of each and every stamp, I collected. There were few politically important stamp and a few with historic importance.
But as a kid, I never knew that. And during our travels and house shifting I have lost that book, which I am regretting now.
I know I won't be able to acquire that many stamps as I had done during my childhood. But yes, that will get replaced by some other hobby for sure.
