Would This Be Considered - Tumblr Posts

Recently my bf told me that his mind doesn't exist pre 1970s the oldest. Like apparently I exist from now all the way back to like, 1700s or older. and So i regularly bring up stuff that happened back then that still effect the world today. & he can't imagine existing pre microwave. he could conceivably be born anywhere between 1970s to today but I could have been born at any time. that's so wild. what the fuck. what does this mean. there has to be a spiritual meaning to this but I haven't soulsearched enough to come up with one. I'm just baffled that bro doesn't regularly consider like 90% of humanity's time on earth. I'm just pondering this conversation that we had like 3 nights ago so i'm not expecting yall to engage but if yall are whats the oldest time period you guys can like, mentally live in? Like that your brain considers when thinking of your world's "big picture"
