no
Paternal grandfather died when I was about 2 (I think of a heart attack, don’t know the age). Maternal grandmother died when I was 12 of a stroke at age 73. Paternal grandmother died when I was 16 of pneumonia at about age 85 (don’t know exact age). Maternal grandfather died when I was 23 of complications from a stroke, but he had Alzheimer’s. He was 73.
16/17
Yes, three. My paternal grandfather died of throat cancer when I was 2. I never met him (there were plans to take me to see him, but I was sick and then he died). My maternal grandmother has inoperable cancer right now but she’s not really dying. My paternal grandmother got cancer a few years ago but it seems to be gone now. Out of all my living grandparents she’s the only one that’s really healthy. I would not be that surprised if the other two kicked the bucket without warning 
I’m 36.
None of my grandparents are currently living.
Both grandfathers died before I was born. My maternal grandmother died when I was 18; my paternal grandmother died this past summer when I was 35.
I also was fortunate enough to know one great-grandmother, who passed away when I was 14.
a) 27
b) Both of my mum’s parents are still alive, and in fairly good health, at 82 and 83. I’ve never met my dad, so don’t know about his side of the family.
I’m 23
I have one living grandparent, she will celebrate her 90th birthday on Saturday.
Both my paternal grandparents died before I was born, my grandmother at the age of 60 from breast cancer (it was the 1970s and if she’d been diagnosed now she would have survived) and my grandfather at the age of 68 from a massive stroke (this was in the 1960s).
My maternal grandfather died 5 years before I was born from a massive stroke, he was 78, and if he was still alive now would be 106…which is unlikely, to say the least.
A factor you haven’t considered is how old your grandparents were when they had children, and how old your parents were when they had you. For example, my maternal grandmother was 30 when she had my father, and my paternal grandfather was in his late 40s. My materal grandfather was 51 when my mother was born, and my maternal grandmother was 35.
My parents were 32 and 38 when they had me, and I’m the eldest of 3.
All of them had children much later than average when compared to their contemporaries, making it much less likely that any grandparents would have survived.
Parents who have children later in life are obviously more likely to die when their children are younger.

Not any more
Maternal grandfather when I was 15. Maternal grandmother about 3-4 years later (not sure, for some reason). Paternal grandfather bored to death by snooker on TV [sup]1[/sup] when I was 22-ish. Paternal grandmother when I was 26, by which time I think she may have been a great-great from at least one of my cousins (I was nearly the last of my generation of her descendants).
1 Well, technically an aortic aneurism at the age of about 88, but he was watching the snooker on TV at the time. Given that he survived a lot of his contemporaries on the Somme by about 67 years, I don’t think he minded too much.
