 We think of altruism as, you know, kind of social-emotional, but I actually first thought of economic harm. So when a caregiver takes on caring for somebody else, there's the cost of hiring help, there's the cost of medical care, there's the cost of leaving the workforce so that you can get care for somebody, because you can, as Mary said, you can no longer, it just is untenable to be working anymore. So when you do that, then you no longer have your health insurance, you no longer have your retirement, you no longer have Social Security accrual, you no longer have all those things that we've come to us, that comes with working, you no longer have your peer group to work with. So there's the, economic harm is huge for caregivers. So I think that's, there's being altruistic and then there's being harmed by that reality. I think there is isolation and one of the things, we had a little dinner before this group and we were, before our meeting here, and we were talking about who's caregiving, and about 40% of caregivers in recent, the Home Alone study, which is people providing chronic care, are millennials. So these are people in the prime of life who are not able to have interaction with their peer group. They are not able to, they're having to run from work to home to caregiving, they can't go out and have a drink with somebody, they can't go out and just have that freedom because they're caring for grandpa or they're caring for a parent who's had, you know, has ALS or MS or some chronic condition where they need to be there in a more present way. And so they're losing, everybody at any age loses capacity, I think, when you don't have social support and a chance to live your life the way that you would like to live. But for somebody right there in the middle of their prime earning years to have to drop out, it's extremely isolated. So I'll just say those two right now, but there's some really, altruism sounds good, but in reality I think there's some real harm on the flip side of that. So I would also say that it's important for people to be altruistic with themselves and that you need to be part of that mix because if you're only altruistic for others then it brings us back to the question here is, so why am I not important or why are you more important than me?
