My condolences for your grandfather. 98 years is a long life, and I figure it must have been a well life.
I hate that I'm born so late, as everything in the "old times" sounds so interesting. And as HeyYou says, the world is getting smaller by each passing year. I certainly don't like every aspect of that! But, there's not much I can say about old times. Old times for my age is when the internet arrived, lol. Hope I will live a long life like your grandfather. As you say, there's so much you can see! (Living to 2100 would have been something, but unless they figure out a treatment to old age, I guess that's a no go...)
