Sarah Silverman has a genuine fear of getting dementia and masturbating in public

Sarah Silverman has revealed that she's got a deep fear of aging and having dementia, especially if it leads to her masturbating in public.

Lots of people are understandably worried about what might happen to them as they get older, as their bodies and minds are no longer quite what they used to be.

Over our lives we go from gurgling potatoes who need a lot of looking after to dynamic beings capable of striding around the world and thinking about some really deep stuff.

Then we get older and the wrinkles start to develop, if you're one of the lucky ones then this might not be very noticeable or you could just go for treatments but that sounds like a lot of time and money to dedicate to something which happens to all of us.

Some people spend an inordinate amount of money trying to prolong youth, but in the annals of history time has managed to nab everyone in the end.

One person who is quite worried about what the future and the aging process holds is Sarah Silverman, who revealed a very specific fear on the Conan O'Brien Needs A Friend podcast.

The actor and comedian mentioned that she felt like she'd run out of things to reveal but then something she'd been talking about before going on the podcast came up, and it turned out to be quite the revelation.

She said: "I have a very, I feel rational, fear of getting dementia and masturbating in public. Very specific.

"Even, every once in a while like every healthy person does, if I do choose to masturbate in a closet alone with several locks I go 'hold on a second, do I have dementia and am elderly and am in a wheelchair at like, my grandson's bar mitzvah right now?'"

Conan pointed out that wondering if you were actually an old person with dementia or at a family gathering were 'not erotic thoughts' that would help a person, as he put it, 'trying to achieve the orgasmic state'.

Silverman joked right back 'that's the only way I can cum', prompting Conan to launch into a bit about how a person would be turned on by 's**tting myself constantly'.

The conversation had already gone pretty weird by this point and it really didn't improve from there, as podcast co-host Sona Movsesian suggested someone really old with dementia could probably get away with that sort of behaviour.

Silverman said that regardless of how much someone elderly and with dementia could be excused for, it was 'definitely not how you want to be remembered' and she felt 'very worried' about the possibility.

Everyone agreed that when they got older they were really looking forward to being a burden on their families and friends.

The host admitted he had wondered if he was developing dementia as he sometimes forgot peoples names and thought he was losing it.

Fortunately for fans of Conan, and presumably the man himself, he's probably not losing his mind as he got chatting to a neurologist who told him humans were 'genetically engineered to remember 140 people's names' and there's just too many people to keep track of these days.
