Any Older Mums Above 40 Here?

I'm 2nd time mum above 40 with a surprise baby. Anyone else here give birth after 40? Do you worry about your kid future as in like we will be 60 when child only teens etc...i can't help but keep having these thoughts. For me it's all over again as my 1st already 11. Maybe I'm still mentally unprepared and worried for what lies ahead.
