No blood related siblings. I have a stepbrother who helped program the Mars rovers though.

I went from being the oldest to the middle sibling to the youngest child over the course of my childhood.

Had a younger brother, then we adopted my cousins as teens, a d a few years later, my brother passed.

Yes, and neither of them use Linux :(

I used to have 7. Down to 4.

Yes, two.... Two years younger and two years older

Three, down to two now. One's 70, the other's 82.

Yep, over a dozen of 'em. Want one?

I have two sisters, one 8 years older and one 2 years younger.

4. All younger… biggest age gap is 15, between me and the youngest (I am 20)

A 56 y/o half-brother that I would do almost anything for and a step-sister that.. well.. whatever.
