As many of you know, the past three years have presented me with challenges in the form of injuries and surgeries. I've worked hard to return to full competitive form. But I also know my body's capacities and limits, and its message to me lately has been clear. I am 41 years old. I have played more than 1,500 matches over 24 years. Tennis has treated me more generously than I ever would have dreamt, and now I must recognize when it is time to end my competitive career.

By the time I admitted that I needed a hip operation, I had denied it for so long that it was a breakthrough to suddenly say, “I need this.” I knew I would probably never dance again, but I had no choice. By that time, I just wanted to be normal. I wanted to walk down the street without limping. I couldn’t tie my shoes. I couldn’t put slacks on. I was the farthest thing from a person who ever could dance and do all those extremely incredible extensions and contortions that we do.

Well, I ran out of gas. You know, I got to be what, 93 at that time, or something like that. And it just – same reason I gave up teaching. I teach – I was – I taught every year from when I was 21 till 88 or 89, and there just came a period when your body said different things to you, and you should turn it over to somebody, just like I did at Berkshire.

As a very young singer, I was invited to the opera house in Berlin by the then-director of the opera house, Egon Seefehlner, and I had one opera to my name that I knew. He felt that there was a lot that I could learn there, which was very true, and I was so lucky to be able to have this opportunity. The thing that was happening is that I kept being offered operas that I knew that I wasn’t ready to sing, just from an experience point of view, as well as being 24 years old. So I was always asked to sing things that I thought, “Well no, I really don’t think I should sing that now. I need to sing that maybe in five years, or maybe in 10 years, but not right now. Couldn’t I please sing something else?” And that became a difficulty for me. And after being at the opera house for three years, and singing Elsa and Elisabeth — the Wagner roles that are not sort of the heavy Wagner roles — and then Mozart operas that suited my voice at the time, I was continually invited to sing things that I just felt I shouldn’t. So I took it upon myself to go to speak with the artistic director to say that I thought I should leave the opera house, and come back in some years when my maturity sort of chronologically would have caught up with the invitations that I was being offered. Of course, considering that he’d taken me into the opera house when I knew one role, he wasn’t all that happy. I thought he’d say, “Oh, what a smart girl. Oh yes, absolutely. That’s what we’ll do.” No, no. He was absolutely furious.

I love swimming and I'll still be found in the pool, but now I'll be able to do without the 04:30 alarm!

When I was in Beijing, London, and also in Rio I was still a kid really, I didn't feel pressure. Now I'm a 26 year old woman. Being a lot older I feel those expectations. And it's definitely hard on my shoulders, to the extent where in training I'm ok but in competitions I panic, and I do stupid things. Working with [my psychologist], at these Games one of the things I'm proud of is I didn't have any panics. I was so happy about that - I went out and raced and enjoyed it.
