If you have any medical issues such as asthma, epilepsy, diabetes, pregnancy, heart problems, (even if they have not occurred recently), then:
- Tell your mates.
- Carry any emergency medication you may require, eg insulin, inhaler. Even if you have not had a problem for a long time.
- It would be useful if you wore a small wristband with medical issues written on it, because it makes it easier for medics to treat you.
