I've never been keen on the sport, because I'm not very big and I'm not all that sporty.
But my older brother was a member of his school's Rugby Team, where he earnt the nickname "Tank" and happened to be known by pretty much everyone by it.
I would recommend you research a little bit about the game, to learn the rules and the terminology.
Rugby Groups tend to be very close-knit groups of friends, and if my brother's rugby group was anything to go by, you won't find more loyal friends elsewhere.
Do you know what sort of position you'd play?
And have you ever played Rugby to any extent before? Beyond just Tag-Rugby in a school PE class.
You might have to be aware that you're in for some knocks and bruises, but so long as you follow the rules and play safe, you'll be fine.
Always wear your safety equipment, like a gum shield.
I would say go for it if you think you'll enjoy it.
Just be careful though. Rugby players tend to get battered quite a bit. They're not the prettiest of fellows.
Busted noses and cauliflower ears aren't uncommon.
I hope you don't ruin your good looks. :P
