Hello
Depending on where you are travelling to I would advise you make sure your vaccinations are up to date. For things like tetanus, and Hep A. Here is a link to a web page we use in UK for such advice.
Hello
If you are travelling to where it is going be very cold, it will be a shock for you. Cover up well, bring along lots of vitamins to protect you, keep well hydrated, and protect your skin especially your lips from the cold air. Don't forget about gloves and hats too. Have a nice time.
