bra: the average life span of a bra is about 6 months.

After exercise, the sports bra should be dried and reused next time. After wearing it for three times, it must be cleaned. Machine washing and roller drying also lead to faster aging of Lycra fabric used to make bra. Therefore, gently rubbing and washing with hands is the best way to clean bra.
bath ball: change it every three months. The bath ball will stick with dead skin and breed bacteria if it is used for a long time. It is recommended to clean thoroughly every 1-2 weeks and change a new bath ball every quarter.
toothbrush: change it every 3-4 months. After use, the toothbrush should be washed and dried vertically. Once the bristles are worn, they should be replaced at any time.

It is better to replace it in time within 3 months, otherwise it will be covered with bacteria.
sports shoes: 8-12 months. I have to change a pair of sports shoes every 1000 kilometers. According to the amount of exercise, the service life of a pair of sports shoes is 8-12 months.
