Starting to run at 52 - is it foolish for the knees?

My doctor said I should be more active. My son said 'just run, dad'. My knees said nothing yet, but I think they have opinions.

I sit at a desk designing all day. Never ran since college. There is a park near my house in Pune with a 1 km loop, quite flat.

Is it better to start with walking and running mixed? Or should I do cycling first? I read on both sides, some say running is bad for knees, some say it make them stronger. I want to hear real experience, not only articles.
