My other thought is that some medications have short term memory problems as a side effect. Is your brother on any medications ? If her is, he could go to www.drugs.com , type in the name of the drug and see if memory issues are a side effect. Finally, is your brother having sleeping problems ?
For some vehicles, you're advised to change the coolant every 30,000 miles. For others, changing the coolant isn't even on the maintenance schedule. For example, Hyundai says the coolant (what many refer to as antifreeze) in most of its models should be replaced after the first 60,000 miles, then every 30,000 miles after that. The interval is every 30,000 miles on some Mercedes-Benz models, but on others it's 120,000 miles or 12 years.
Card Replacement. The SSA will replace a card for free up to three times yearly with a limit of 10 times in a lifetime. A replacement card for a name change that involves a marriage, an adoption, or a legal name change does not count against the 10 replacement. 1. Fill out a SSA Form SS-5, Application for a Social Security Card, found at www.ssa.gov/online/ss-5.pdf. The form is used for new, replacement and name change cards. 2. Submit the form with one official, original or certified, document that verifies your identify.
