The Hello welcome to a special naked scientist's question and answer

edition with me Chris Smith joined by Ginny Smith and Dave Ansel.

Also with us this week is special guest,

the insect expert Ian Burgess,

and we'll be talking with him about daddy longlegs

a little bit later in the program as well

as fielding your science questions including Orden, do fit people sweat more?
