If the cause of earache is an ear infection, there may be a watery or pus-like fluid coming out of the ear. Outer ear infections (infections of the tube connecting the outer ear and eardrum) and middle ear infections (infections of the parts of the ear behind the eardrum) are very common causes of earache.
Umbrella company contractors only have to keep personal tax records, as they are employees, not business owners. If you are an employer, you need to keep all PAYE records for 3 years (in addition to the current year). A CIS contractor must keep his CIS records for the same period of time.
The CISSP certification has a three-year lifespan. Consequently, it is imperative that you make time for at least 120 continuing professional education (CPE) credits within each three-year interval. Of these 120 credits, at least 80 must be Type A, or directly relating to the information security profession.
