I work with colour a lot (theory, psychology, application, etc) and some years ago remember reading a piece in the BMJ about a medical research project related to colour impairment... I feel sure that the piece said that around 30% of males are either colour 'blind' or have some level colour impairment... I can't for the life of me find any evidence of this study online, so maybe there is new evidence that that takes the % back down to one in ten males... anyone know any thing about this?

Top left might be a 5 and 8?...

Top right defo 18...

Bottom left, nae chance...

Bottom right 1 and 7 or maybe 2?...


On the subject of lefties, there was a boy at my school who was naturally left handed, and he reckoned a doctor said he had developed a stammer because his parents tried to get him to use his right hand/foot when he was younger!..

BBW, I too have been tempted but saw the effects and read too much and saw too many photos. I drew my own conclusions and feel nightmares like that should be left in the past, if possible.


Is the diagram not 58, 18, E and 17?


Agreed Red Devil, never try to change the hand/foot that children use. I think it confuses them.

That happened to my grand-dad. I'm not sure what year he was born, but some time around the turn of the century. I understand that teachers would tie his left hand to his side. Anyway, he stammered all his life because of it, but had a lovely tenor singing voice, without stammer.


Edited to say - sorry for going (and remaining) off topic - I have never chewed gum!

If the first answer is "8" then I got the first two only.


The second, I assume is "10" no idea about the 3rd or 4th one.

    • This may be somewhat out of date but virtually no environmental benefit & almost entirely grass... really? https://www.gigl.org.uk/sinc/sobi09/ Description Peckham Rye was established as an open space in the late 19th century and includes several valuable habitat features spread across the park. The park is a Grade II Listed landscape, and has recently been restored with assistance from the Heritage Lottery Fund. A small community garden within the site is managed by the Friends of Peckham Rye. Peckham Rye Park won a Green Flag Award again for 2022. The site is used by the Southwark Health Walks project as part of a Walking the Way to Health (WHI) scheme. Wildlife This large park has several valuable habitat features. The most important of these is the only remaining above-ground section of the River Peck and the most natural stream in the borough. The stream is heavily shaded by native, unmanaged wet woodland dominated by alder, ash and pedunculated oak with a ground cover of pendulous sedge and bramble. Alder dominated woodland is a rare habitat in Southwark. Although somewhat altered with weirs, other artificial structures and ornamental planting, some sections are still in their natural banks and includes yellow flag, watercress, water figwort and cuckooflower. The largest of three ponds supports marginal vegetation including hemp agrimony. A variety of waterfowl nest on the wooded island, including tufted duck, coot, Canada goose and mallard. Substantial flocks of gulls visit the park in winter and bats are likely to forage over the water. Small blocks of predominantly native woodland, mostly on the boundary between the Park and the Common, are dominated by oak and ash with a well-developed understory, but sparse ground flora. Spring bulbs have been planted in previous years. These and several dense shrubberies support a good bird population and small numbers of pipistrelle bats are present. Infrequently mown grassland is located in one large area and was seeded in 2009. It's composition includes giant fescue, ladies bedstraw, meadowsweet, black knapweed and wild carrot. The rest of the park consists of amenity grassland with some fine mature trees.  
    • Same here. Incredibly selfish behaviour. Also illegal.
    • I heard them & our two dogs were extremely upset by it..  bad enough during the evenings but at least can have music on to dilute the noise!   Some people have literally zero thoughts for others!! 
    • I have signed that petition.  Someone was letting off loud fireworks at about 3 am this morning. They woke me up.   I don’t know where they were exactly but it sounded like they were in the vicinity of Dog Kennel Hill.
