Is there a reference frame where our entire life happens simultaneously?

[phone33]

I have think I might have a feeble grasp on the idea that simultaneity of events at different points of space depends on the reference frame. However I was having a conversation with my friend and we were trying to figure out if there would be a reference frame where our whole life happened simultaneously. That just seems odd to me but he pointed out that nothing we do is ever really in the same point in space due to our orbit around the sun/galactic center/cluster center/ who knows what else.

Any thoughts on if such a frame exists, also if some one had a reference to a place that this is explained because I doubt he will buy my "Some person on the forums said..." argument.

Sorry if this is a repost i know people can frown on that.

Simultaneity is frame dependent for non-causally connected events. For events on a worldline (timelike path, e.g. your path through spacetime), all observers agree on sequential time order of the events of your life.

In a very real sense, there isn't any such frame, because the interval between you-now, and you-one-year-older is always one year, which is a non-zero value.

You can find ill-behaved coordinate systems that assign the same time coordinate to you-now and you-one-year-older if you look. People occasionally run into trouble when they take such badly behaved coordinates too seriously, rather than realizing that said coordinates are badly behaved because they assign the same time coordinate to demonstratably different events (you-now, and you-one-year-older).
