Hi all, I'm 77 years old and I enjoy good health and have a brisque 90 minutes walk every morning. The 2 things I hate is of course the soi dogs and those dreaded footpath paving bricks. The original pavers were set perfectly but then along comes the people who do repairs to water connections etc but never reset the pavers properly. Many look fine but have no compacted soil underneath them. You stand on them and on your bum go. Cheers.
