I had an older F, too, though not all that old by today’s standards. He was 42 when I was born and died when I was 28. I never thought of that as being unusual tbh. (Although he was abusive which colours my view somewhat.)
He was in poor health, suffered from Parkinson’s for many years and also had several strokes. Not lifestyle related.
I guess another reason why I never thought about it being unusual was that my DM was orphaned at 10, and by the time I was 3, all my grandparents were dead.
Despite this, my DH and I are older parents, by adoption. I was 40 when DD1 came to us at age 1 and my DH was 44. I realise that this isn’t ideal, but it’s the way things worked out after years of infertility. Thankfully, my 2 DDs (16 and 13) have 2 grandmas who are very much alive in their 80s, though my MIL has recently been diagnosed with dementia.
IMO I’m an older mum. I couldn’t imagine starting at the OP’s age! I’m sorry, but it really is a bad idea, especially as she’s on her own.
