ventilation and the virus joining me now is paul linden he's professor of fluid mechanics at cambridge university paul it's good to have you on the show. with the obvious question winter is approaching in northern in the northern hemisphere what's the best thing that someone should keep in mind about ventilation in rooms well it's obviously a challenge the winter because. c. is too close up buildings and ventilation is reduced to keep warm so the best thing to do is to make sure that as much ventilation as possible is achieved open a window if you possibly can. and if you have a mechanical system make sure as much fresh air coming in as possible what about fans what if i just have fans that are standing around the room does that help keep things ventilators that help me at all. no it doesn't it will just mix up what's already there and that's probably not the best thing because if there is virus particles in the air in the air and start all around your chances of breathing them are increased so i wouldn't recommend using fans ok so the best option and it seems to be is to keep the window open even tho

paul robinson public and international affairs professor us also university. people in their thirty's around the world significantly less faith in democratic institutions than previous generations that's according to a survey by cambridge university researchers quizzed close to $5000000.00 people in $160.00 countries the study run for nearly 5 decades through large canvas people around the age of 30 about their views on democracy each subsequent generation of 30 somethings reported less office faction trust in political systems we asked people in paros london and some francisco if they think democracy in its current form is fit for purpose where they live. i don't necessarily believe that it works the way. i still believe in democracy but you don't have confidence in the current government for democracy is there but i don't think it's being implemented properly i think the state of democracy is more risk than it has been before this system is looking increasingly like a dictatorship to me personally i think it's true that it's all broken. parents don't educate him enough but i can say kind of because we're not really in in any more our generation isn't there you see people that are. 506070 that are running the governme

paul, this next one from cambridge. she says my daughter is at sheffield university and is disabled. sheffield, as we know, is tier 3.lt question. you are allowed to visit, move into different tiers for the purposes of caring responsibilities, is the exact phrase. i think... the difficulty is how much caring responsibilities count. so if you are using it as an excuse just to visit your daughter, then probably the answer is no. but if your daughter really does need you to go and care for her then certainly i would, in that context, continue to visit my daughter. but you can't pretend it's for caring and actually it's a social visit. i think to be fair, she says we want to visit as carers, so fair, she says we want to visit as carers, so i think we give her the benefit of the doubt. yes, with the benefit of the doubt. yes, with the benefit of the doubt, absolutely she can visit. but with the proviso that it actually has to be for caring. right. jillian, this from sheffield again. my 18—year—old daughter and herfriend were again. my 18—year—old daughter and her friend were planning to go to london at half time to do som
