How trustworthy is your fitness tracker score
- Composite health scores provided by fitness trackers are increasingly used to offer a simplified measure of how the body is coping with recent demands.
- The science behind these scores may be less solid than it appears due to factors such as sensor accuracy and lack of transparency in how the raw data is converted into a final score.
- Some health scores may penalize users for similar physiological signals twice, exaggerating the impact of a particular stressor.
- While fitness trackers can provide valuable insights, it is important not to treat the daily score as a definitive measure of health and to use them as a guide rather than relying on them completely.

Trump’s Tariff Exemption for Tech Products Could Be Short-Lived
- President Donald Trump has exempted electronics from the 'reciprocal' tariffs imposed on China, but they will be included in separate tariffs on semiconductors in the future.
- U.S. Commerce Secretary Howard Lutnick stated that electronics goods like smartphones would eventually fall under the upcoming semiconductor tariffs.
- The exemption of electronics from current tariffs could be short-lived, potentially resulting in the return of tariffs on products like iPhones in a few weeks.
- This decision may generate further business uncertainty, as the government has reversed course on tariffs in the past, leading to market turmoil and sell-offs in the U.S. Treasurys market.
