Sangroper - get a lighter whippy.
Chris - Spot on mate, stretch and sip (hydrate in new-speak) Do a bit of a regular workout and find a good chiropractor.
Smashed my elbow years ago on a bike prang so wouldn't know tennis elbow if it bit me, but watch out for "tennis leg"
Usually hits blokes late 40's when the muscles start to calcify. There is a rotator muscle in the calf (from the achilles) that we are prone to snap due to our work hardened muscles. Stretching might help, but I've snapped both mine so wouldn't know. You'd swear someone teed off with a # 1 wood right into the back of your leg with a golf ball. There's a "crack" and you are in a lot of pain struggling to walk for the next 3 days. Takes about a month before you walk reasonably smoothly again.
When doing a fair bit of heavy lifting wear a decent gut belt (wide leather belt) and lift properly. Like Steve, I'm on the 3rd hernia (left, right and now umbilical from coughing with pnumonia of all things )
Cramps and aches - vitamin tablet every day, thick vegemite on toast for brekkie (salt and vitamin Fruit saline for after work to rehydrate and replace salt.
Good leather boots and thick socks to keep away fungal problems and sprained ankles.
Wear decent sun protection and get the cancers burnt off each winter.
Even with the best hearing protection you will get some hearing loss, but use the best earplugs you can get.
We are at risk of Kidney stones from being dehydrated a lot - bloody painful as. Doc reckons worse than childbirth.
I was stubborn and wouldn't go for surgery. (Wollongong hospital you come out worse than you go in). After 3 days I shifted the stones by drinking pint mugs of straight lemon juice to dissolve them and jarred them along by jumping hard off the verandah onto concrete. (it works - better than surgery)
3x lots of broken ribs, smashed ankle, chainsawed thumb, concussions = just dumb mistakes.
5 minutes thought is better than 5 hours stuff up or 5 weeks off work injured.
