Life was different? Was his advice just for that time and that TIME only? If you say YES to that question, there is no further discussion since you have your mind set on it.
But on the other hand if you believe that Prophet Muhammad (pbuh)'s message was for ALL generations until the day of judgment, then the marriage advice STILL STANDS, even more so in this day and age.
Let’s not even get into the details of gender issues and what each gender has to face individually.. That’s a whole another discussion.
One thing, many women will agree, that as a woman gets older, it’s harder for her to have children or even raise them. Life1 is a good example, where you see cases of single women in their late 30s even 40s not married. I don’t want to generalize here but I find some cases are due to the pursuit of higher education / jobs and ignoring/putting marriage off for the “future”.
just my twocents.
