Loving The Gentleman but can't get over the continuity error where Vinnie Jones uses a CB radio with no antenna coaxial plugged into it. Just power.

Can't imagine how I ended up with a bone stress injury. Absolutely baffling. 🤔😂 In completely unrelated news, apparently I ran nearly 360km in August. Foot is finally feeling much better though. Lesson learned: recovery is training too. 🏃‍♂️ #runsky #londonmarathon

I'm running the London Marathon! 🏃‍♂️ At the beginning of this year, I wouldn't have believed anyone who told me I'd be writing this! I started running regularly to lose weight and get fitter. Since

Moving to a new phone still isn't simple. Used androids transfer wizard. Kinda does less than a quarter of a job and still leaves you with hours of logins and reauths etc. #newworldproblems

Hey #fitnesssky how often do you change your running shoes? And/or do you alternate? Different shoes for different runs?

Really pleased with my #parkrun progress. Running used to be sporadic, but since February I’ve been consistent ... most mornings plus some strength work in the gym. Down 9kg so far. Turned 54 in January and decided it was time to properly get back on top of my health. #fitnesssky

Strava's AI is terrible because it doesn't take into account your goals. Constantly telling me I'm slower than usual when I was running an intentionally slower base run. Strava seems to want you to always be faster ...

So I built a thing for instructors to handle class bookings: classta.co ... my partner does trigger point pilates classes and tried a bunch of other class/event schedulers but found them difficult to use or not flexible enough. So I went and built another one.

Cinema is struggling to compete with streaming services in our own lounges as it is so when my cinema seat has a broken arm rest and is angled forwards trying to tip me out and all the staff can suggest is I wait for the film to start and then change seats, it doesn't really compute.

Hello, Jon. 

This is Spotify headquarters. Although this presentation is typically automatically generated, we find these circumstances so extraordinary that we felt the need to reach out to you with a personal message. We have found that while you did listen to rap music this year, you listened to country music as well. This is a music listening pattern of such rare precedent that we were compelled to disconnect our servers, lest our algorithm crash them entirely upon attempting to categorize your tastes. You are the most interesting person we have ever encountered, and we wish the incurious blockheads who make up the remainder of our subscriber base shared not only your adventurous spirit, but fearless authenticity. We have your banking information on file. As a token of our appreciation, $5,000,000 USD will be deposited into your account immediately. 

Thank you for everything, Jon.

New data on farms and inheritance tax: a third of farm estates over £1.5m aren’t farmers but wealthy people avoiding IHT by sinking money into farmland. The Budget hits farmers too hard and tax avoiders too lightly. It needs to change.

When you see a stack of pancakes on the table in films/tv. Sorry but no. They'd be cold. You have to eat a pancake within seconds of it coming out of the pan. And as for toast racks ... same deal, what the?
