[power tools] I am most comfortable talking about technology.

You know I've got a a endless desire to know how things work and I seem to think that I know how to make everything better.

So whenever I get something I know it's not doing it right then I want to make it better.

[Laughing] Gerda: OK. How does it go again?

One ... two Peter: Like this.

One.

Two.

Three.

Tap.

Both: One.

Peter: Gerda's really a part of my daily living and it's been like that for a long time.

Gerda was very good at looking after our relationship.

But, um, lately I feel that there's been a little bit of a shift over to me.

Gerda: ... in the middle between the two of them.

Peter: O.K.

I think that's about right ... Of course, it's hard for me to see Gerda losing some of her capabilities because she's always been the smartest person I've ever known.

The only way that I can try and do something about it is to provide, um, tools to move forward with but I know it's getting worse and worse and worse and I can see it all the time and, you know, it's very sad.

Gerda: Sweetie?

Peter: So what have you got going here?

Peter: These are just links Gerda: So I can't do anything ...

I don't want to do Peter: Categories... Gerda: Where is that?

Gerda: Oh sweetie, I just get confused.

Peter: So I like to fix things ... You know, setting things up for her and letting her be able to make life easier for her is a pleasure for me.

And it is nice for me because it's essentially a puzzle I love puzzles, OK?

Interviewer: But there's one thing you can't fix.

Peter: Yeah, that's right.

So, um... That is kind of sad and I, uh, I don't really...

I try not to dwell on it but I do cry a lot, OK?

But I focus on the things that are interesting and exciting and stuff that we can still do.

But, you know, seeing Gerda going backwards is not fun.

Gerda: Dammit.

I can't find it.

Peter: Do you want me to look here?

Gerda: No, why don't you just find it your own way.

I just got, I'm gonna to go to the bathroom.

Okay.

Peter: Alright.

[door shuts] Peter: She says that her life will be over when her brain is in such a position that, for example, she cannot recognize people.

For example, if she cannot manage her life in such a way that, you know, somebody has to look after 24 hours a day.

These are kind of things which she said this is who Gerda is.

This is who I am, and if I'm not that then I don't, I don't think life is worth living.

And she's asked, you know, will you help me because I most probably at that point will not be able to make a decision that I want to end life.

You know if you think about it it's, it's hard to think that you're going to ... kill somebody that you love so much and ... very hard.

But ... um ... you know, I will do it.

I've promised.

And I will.

[piano music] [milk falling] Gerda: Sorry [piano music] Peter: We've had lots of discussions about, you know, I don't want you to fix this just listen to me, let's talk about it.

And that is very hard.

You know, I want to buy electronics or gadgets or make things in the garage to help her solve her problems.

I thought I'd use the drone to sweep up the leaves in the driveway.

Gerda: He blows them but just not consistently in one direction.

[Peter laughing.]

Peter: This is a path that I cannot change and I need to figure out how to walk down this path with her.
