My dad had me at his 60s. Now he's 90. I do not want to sound ungrateful - he gave me a lot and I am happy that he's still around, but I wish he was younger back then. We've never done some activities as a family, like travel abroad. And unfortunately in the last 5 years, he lost a lot of energy and he's starting to suffer with dementia, sleeping most of the time.
