Eggs are good nutritionally and an excellent source of protein. Eating eggs will not give high cholesterol levels unless they are fried, as the oil will raise cholesterol levels.
The British Heart Foundation advice is that you can eat as many as you like (boiled, scrambled, poached, omelettes and in cakes and puddings) within a varied diet.

Salt facts
We currently eat too much salt in our diet. If we cut our daily intake from around 9g ( a teaspoon and a half) a day to the recommended 6g (around a teaspoon) a day, then 35,000 heart attacks and strokes could be prevented each year in the UK.
Don't forget that a lot of salt is hidden in ready meals, tinned foods and cakes, biscuits, bread, pies, etc.
If you have a food allergy or coeliac disease, some wheat and dairy-free products have extra salt compared with levels in standard products, so read labels carefully.

Lead - Link with Drop in Crime Rates
For most of the 20th Century crime rose and rose and rose. Then, about 20 years ago, the trend reversed - and all the broad measures of key crimes have been falling ever since.Offending has fallen in nations whose governments have implemented completely different policies to their neighbours. If your nation locks up more criminals than the average, crime has
fallen. If it locks up fewer... crime has fallen. Nobody seems to know
for sure why.
Some people that believe the removal of lead from petrol was a key factor. Lead can be absorbed into bones, teeth and blood. It causes kidney damage, inhibits body growth, causes abdominal pain, anaemia and can damage the nervous system. Exposure to lead during pregnancy reduces the head circumference of infants. In children and adults, it causes headaches, inhibits IQ and can lead to aggressive or dysfunctional behaviour. In other words - lead poisoning leads to bad decisions. The lead theorists say the poison has a time-lag effect which could not be understood until recently.
Research by Prof Jessica Wolpaw-Reyes, an economist at Amherst College Massachusetts, tested if there was a causal link between lead and violent crime by looking at the removal of leaded petrol from US states in the 1970s, to see if that could be linked to patterns of crime reduction in the 1990s. Wolpaw-Reyes gathered lead data from each state, including figures for gasoline sales. She plotted the crime rates in each area and then used common statistical techniques to exclude other factors that could cause crime. Her results showed that states that experienced particularly early or particularly sharp declines in lead experienced particularly early or particularly sharp declines in violent crime 20 years later. The research also established different levels of crime in states with high and low lead rates. This relationship is now coming up in other work on bullying, child behaviour problems, teenage delinquency, suicide and substance abuse.
Supporters of the theory predicted that crime would fall in other nations 20 years after the banning of leaded petrol - and their theory appears to have played out in Europe. Leaded petrol was removed from British engines later than in North America - and the crime rate in the UK began to fall later than in the US and Canada. Lead theorists say that data they've collated and calculated from each nation shows the same 20-year trend - the sooner lead is removed from the environment, the sooner crime will begin to fall. Data now suggests that lead could account for as much as 90% of the changing crime rate during the 20th Century across all of the world.
The debate among biologists is now moving further, to look at how improving nutrition could affect antisocial behaviour. Lead is unlikely to be the whole story but given the broad worldwide exposure and the evidence of how adversely lead can affect behaviour, it makes sense that it is an important part of the story.

Cystitis
Cranberry can help prevent attacks. A daily dose of high strength cranberry extract (400mg) is likely to be more effective than drinking cranberry juice.

Digital TV Future
A more sophisticated sytem for broadcasting digital TV (DDT) is being developed and is scheduled for switchover in 2018. At the same time, Freeview and radio channels are to be switched to another part of the broadcasting spectrum.
The shift to a more sophisticated system and the planned switching of channels would not be compatible with millions of TVs and set top boxes, so many users are likely to need new equipment to receive programmes, and it is thought that up to 30% of homes might need a new aerial.
By the end of 2018, industry forecasts expect 80% takeup of primary sets to DVB-T2/MPEG-4 receivers.
Moving the Freeview channels will face broadcasters like BBC, ITV and Channel 4 with huge costs to change their masts and broadcasting technology.
